+        *
+        * <p>The method executes the following steps:
+        * <ol>
+        *   <li>Validates the input username parameter</li>
+        *   <li>Creates a delete-by-query request with term query matching</li>

+        *   <li>Returns the operation status based on number of deleted documents</li>
+        * </ol>
+        *
+        * <p>Example query structure:
+        * <pre>
+        * {

+# Resource Sharing and Access Control Plugin
+
+This plugin demonstrates resource sharing and access control functionality, providing APIs to create, manage, and verify access to resources. The plugin enables fine-grained permissions for sharing and accessing resources, making it suitable for systems requiring robust security and collaboration.
+
+## Features
+
+- Create and delete resources.
+- Share resources with specific users, roles and/or backend_roles with specific scope(s).
+- Revoke access to shared resources for a list of or all scopes.
+- Verify access permissions for a given user within a given scope.
+- List all resources accessible to current user.
+
+## API Endpoints
+
+The plugin exposes the following six API endpoints:
+
+### 1. Create Resource
+- **Endpoint:** `POST /_plugins/sample_resource_sharing/create`
+- **Description:** Creates a new resource. Also creates a resource sharing entry if security plugin is enabled.
+- **Request Body:**
+  ```json
+  {
+    "name": "<resource_name>"
+  }
+  ```
+- **Response:**
+  ```json
+  {
+    "resource_id": "<resource_id>",
+    "status": "created"
+  }
+  ```
+
+### 2. Delete Resource
+- **Endpoint:** `DELETE /api/resource/{resource_id}`
+- **Description:** Deletes a specified resource owned by the requesting user.
+- **Response:**
+  ```json
+  {
+    "resource_id": "<resource_id>",
+    "status": "deleted"
+  }
+  ```
+
+### 3. Share Resource
+- **Endpoint:** `POST /api/resource/{resource_id}/share`
+- **Description:** Shares a resource with specified users or roles with defined permissions.
+- **Request Body:**
+  ```json
+  {
+    "share_with": [
+      { "type": "user", "id": "user123", "permission": "read_write" },
+      { "type": "role", "id": "admin", "permission": "read_only" }
+    ]
+  }
+  ```
+- **Response:**
+  ```json
+  {
+    "resource_id": "<resource_id>",
+    "status": "shared"
+  }
+  ```
+
+### 4. Revoke Access
+- **Endpoint:** `DELETE /api/resource/{resource_id}/revoke`
+- **Description:** Revokes access to a resource for specified users or roles.
+- **Request Body:**
+  ```json
+  {
+    "revoke_from": [ "user123", "role:admin" ]
+  }
+  ```
+- **Response:**
+  ```json
+  {
+    "resource_id": "<resource_id>",
+    "status": "access_revoked"
+  }
+  ```
+
+### 5. Verify Access
+- **Endpoint:** `GET /api/resource/{resource_id}/verify`
+- **Description:** Verifies if a user or role has access to a specific resource.
+- **Query Parameters:**
+    - `user_id` (optional): ID of the user.
+    - `role` (optional): Role to verify.
+- **Response:**
+  ```json
+  {
+    "resource_id": "<resource_id>",
+    "access": true,
+    "permissions": "read_only"
+  }
+  ```
+
+### 6. List Accessible Resources
+- **Endpoint:** `GET /api/resources/accessible`
+- **Description:** Lists all resources accessible to the requesting user or role.
+- **Response:**
+  ```json
+  [
+    {
+      "resource_id": "<resource_id>",
+      "name": "<resource_name>",
+      "permissions": "read_write"
+    },
+    {
+      "resource_id": "<resource_id>",
+      "name": "<resource_name>",
+      "permissions": "read_only"
+    }
+  ]
+  ```
+

+# Resource Sharing and Access Control Plugin
+
+This plugin demonstrates resource sharing and access control functionality, providing APIs to create, manage, and verify access to resources. The plugin enables fine-grained permissions for sharing and accessing resources, making it suitable for systems requiring robust security and collaboration.
+
+## Features
+
+- Create and delete resources.
+- Share resources with specific users, roles and/or backend_roles with specific scope(s).
+- Revoke access to shared resources for a list of or all scopes.
+- Verify access permissions for a given user within a given scope.
+- List all resources accessible to current user.
+
+## API Endpoints
+
+The plugin exposes the following six API endpoints:
+
+### 1. Create Resource
+- **Endpoint:** `POST /_plugins/sample_resource_sharing/create`
+- **Description:** Creates a new resource. Also creates a resource sharing entry if security plugin is enabled.
+- **Request Body:**
+  ```json
+  {
+    "name": "<resource_name>"
+  }
+  ```
+- **Response:**
+  ```json
+  {
+    "message": "Resource <resource_name> created successfully."
+  }
+  ```
+
+### 2. Delete Resource
+- **Endpoint:** `DELETE /_plugins/sample_resource_sharing/{resource_id}`
+- **Description:** Deletes a specified resource owned by the requesting user.
+- **Response:**
+  ```json
+  {
+    "message": "Resource <resource_id> deleted successfully."
+  }
+  ```
+
+### 3. Share Resource
+- **Endpoint:** `POST /_plugins/sample_resource_sharing/share`
+- **Description:** Shares a resource with specified users or roles with defined scope.
+- **Request Body:**
+  ```json
+    {
+      "resource_id" :  "{{ADMIN_RESOURCE_ID}}",
+      "share_with" : {
+        "SAMPLE_FULL_ACCESS": {
+            "users": ["test"],
+            "roles": ["test_role"],
+            "backend_roles": ["test_backend_role"]
+        },
+        "READ_ONLY": {
+            "users": ["test"],

 This plugin demonstrates resource sharing and access control functionality, providing sample resource APIs and marking it as a resource sharing plugin via resource-sharing-spi. The access control is implemented on Security plugin and will be performed under the hood.
 
+## PreRequisites
+
+Publish SPI to local maven before proceeding:
+```shell
+./gradlew clean :opensearch-resource-sharing-spi:publishToMavenLocal
+```
+
 ## Features
 
 - Create, update and delete resources.

-    * <ol>
-    *   <li>Validates input parameters for null/empty values</li>
-    *   <li>Creates a search request with a bool query for exact matching</li>
-    *   <li>Executes the search with a limit of 1 document</li>
-    *   <li>Parses the result using XContent parser if found</li>
-    *   <li>Returns null if no matching document exists</li>
-    * </ol>

-    *
-    * @param pluginIndex The source index to match against the source_idx field
-    * @param resourceId The resource ID to fetch. Must exactly match the resource_id field
-    * @param listener The listener to be notified when the operation completes.
-    *                 The listener receives the parsed ResourceSharing object or null if not found

-    *   <li>Uses term queries for exact matching</li>
-    *   <li>Expects only one matching document per resource ID</li>
-    *   <li>Uses XContent parsing for consistent object creation</li>

-# Resource Sharing and Access Control SPI
+# Resource Sharing Client
 
-This Client package provides ResourceSharing client to be utilized by resource plugins to implement access control by communicating with security plugins.
+This Client package provides a ResourceSharing client to be utilized by resource plugins to implement access control by communicating with security plugin.
+
+## Usage
+
+1. Create a client accessor with singleton pattern:
+```java
+public class ResourceSharingClientAccessor {
+    private static ResourceSharingNodeClient INSTANCE;
+
+    private ResourceSharingClientAccessor() {}
+
+    /**
+     * Get resource sharing client
+     *
+     * @param nodeClient node client
+     * @return resource sharing client
+     */
+    public static ResourceSharingNodeClient getResourceSharingClient(NodeClient nodeClient, Settings settings) {
+        if (INSTANCE == null) {
+            INSTANCE = new ResourceSharingNodeClient(nodeClient, settings);
+        }
+        return INSTANCE;
+    }
+}
+```
+
+2. In your transport action doExecute function call the client.
+Here is an example implementation of client being utilized to verify delete permissions before deleting a resource.
+```java
+@Override
+protected void doExecute(Task task, DeleteResourceRequest request, ActionListener<DeleteResourceResponse> listener) {
+
+    String resourceId = request.getResourceId();
+    ResourceSharingClient resourceSharingClient = ResourceSharingClientAccessor.getResourceSharingClient(nodeClient, settings);
+    resourceSharingClient.verifyResourceAccess(
+        resourceId,
+        RESOURCE_INDEX_NAME,
+        SampleResourceScope.PUBLIC.value(),
+        ActionListener.wrap(isAuthorized -> {
+            if (!isAuthorized) {
+                listener.onFailure(new ResourceSharingException("Current user is not authorized to delete resource: " + resourceId));
+                return;
+            }
+
+            // Authorization successful, proceed with deletion
+            ThreadContext threadContext = transportService.getThreadPool().getThreadContext();
+            try (ThreadContext.StoredContext ignored = threadContext.stashContext()) {
+                deleteResource(resourceId, ActionListener.wrap(deleteResponse -> {
+                    if (deleteResponse.getResult() == DocWriteResponse.Result.NOT_FOUND) {
+                        listener.onFailure(new ResourceNotFoundException("Resource " + resourceId + " not found."));
+                    } else {
+                        listener.onResponse(new DeleteResourceResponse("Resource " + resourceId + " deleted successfully."));
+                    }
+                }, exception -> {
+                    log.error("Failed to delete resource: " + resourceId, exception);
+                    listener.onFailure(exception);
+                }));
+            }
+        }, exception -> {
+            log.error("Failed to verify resource access: " + resourceId, exception);
+            listener.onFailure(exception);
+        })
+    );
+}
+```

 ## Usage
 
-A plugin defining a resource and aiming to implement access control over that resource must extend ResourceSharingExtension class to register itself
+A plugin defining a resource and aiming to implement access control over that resource must extend ResourceSharingExtension class to register itself as a Resource Plugin. Here is an example:
+
+```java
+
+public class SampleResourcePlugin extends Plugin implements SystemIndexPlugin, ResourceSharingExtension {
+
+    // override any required methods
+
+    @Override
+    public Collection<SystemIndexDescriptor> getSystemIndexDescriptors(Settings settings) {
+        final SystemIndexDescriptor systemIndexDescriptor = new SystemIndexDescriptor(RESOURCE_INDEX_NAME, "Sample index with resources");
+        return Collections.singletonList(systemIndexDescriptor);
+    }
+
+    @Override
+    public String getResourceType() {
+        return SampleResource.class.getCanonicalName();
+    }
+
+    @Override
+    public String getResourceIndex() {
+        return RESOURCE_INDEX_NAME;
+    }
+
+    @Override
+    public ResourceParser<SampleResource> getResourceParser() {
+        return new SampleResourceParser();
+    }
+}
+```
+
+Checklist for resource plugin:
+1. Add a dependency on `opensearch-security-client` and `opensearch-resource-sharing-spi` in build.gradle.
+2. Declare a resource class and implement `Resource` class from SPI.
+3. Implement a `ResourceParser`.
+4. Implement `ResourceSharingExtension` interface in the plugin declaration class, and implement required methods (as shown above). Ensure that resource index is marked as a system index.
+5. Create a client accessor that will instantiate `ResourceSharingNodeClient`.
+6. Use the methods provided by `ResourceSharingNodeClient` to implement resource access-control.

 Checklist for resource plugin:
 1. Add a dependency on `opensearch-security-client` and `opensearch-resource-sharing-spi` in build.gradle.
-2. Under `src/main/resources` folder of the plugin, and declare a file named `org.opensearch.security.spi.resources.ResourceSharingExtension`. Edit that file to add single line containing classpath of your plugin, e.g `org.opensearch.sample.SampleResourcePlugin`. This is required to utilize Java's Service Provider Interface mechanism.
+2. Under `src/main/resources` folder of the plugin, locate or create a folder `META-INF/services`and in the services folder, declare a file named `org.opensearch.security.spi.resources.ResourceSharingExtension`. Edit that file to add single line containing classpath of your plugin, e.g `org.opensearch.sample.SampleResourcePlugin`. This is required to utilize Java's Service Provider Interface mechanism.
 3. Declare a resource class and implement `Resource` class from SPI.
 4. Implement a `ResourceParser`.
 5. Implement `ResourceSharingExtension` interface in the plugin declaration class, and implement required methods (as shown above). Ensure that resource index is marked as a system index.

+# **Resource Sharing and Access Control in OpenSearch**
+
+This guide provides an **in-depth overview** for **plugin developers**, covering the **features, setup, and utilization** of the **Resource Sharing and Access Control** functionality in OpenSearch.
+
+## **1. What is the Feature?**
+The **Resource Sharing and Access Control** feature in OpenSearch Security Plugin enables fine-grained access management for resources declared by plugins. It allows:
+- Users to **share and revoke access** to their own resources.
+- **Super admins** to access all resources.
+- Plugins to **define and manage resource access** via a standardized interface.
+
+This feature ensures **secure** and **controlled** access to resources while leveraging existing **index-level authorization** in OpenSearch.
+
+---
+
+## **2. What are the Components?**
+This feature introduces **two primary components** for plugin developers:
+
+### **1. `opensearch-security-client`**
+- Provides a client with methods for **resource access control**.
+- Plugins must declare a **dependency** on this client to integrate with security features.
+
+### **2. `opensearch-resource-sharing-spi`**
+- A **Service Provider Interface (SPI)** that plugins must implement to declare themselves as **Resource Plugins**.
+- The security plugin keeps track of these plugins (similar to how JobScheduler tracks `JobSchedulerExtension`).
+
+### **Plugin Implementation Requirements:**
+
+- This feature is marked as **`@opensearch.experimental`** and can be toggled using the feature flag: **`plugins.security.resource_sharing.enabled`**, which is **enabled by default**.
+- **Resource indices must be system indices**, and **system index protection must be enabled** (`plugins.security.system_indices.enabled: true`) to prevent unauthorized direct access.
+- Plugins must declare dependencies on **`opensearch-security-client`** and **`opensearch-resource-sharing-spi`** in their `build.gradle`.
+
+### **Plugin Implementation Requirements**
+Each plugin must:
+- **Implement** the `ResourceSharingExtension` class.
+- **Ensure** that its declared resources implement the `Resource` interface.
+- **Provide a resource parser**, which the security plugin uses to extract resource details from the resource index.
+- **Register itself** in `META-INF/services` by creating the following file:
+  ```
+  src/main/resources/META-INF/services/org.opensearch.security.spi.ResourceSharingExtension
+  ```
+    - This file must contain a **single line** specifying the **fully qualified class name** of the plugin’s `ResourceSharingExtension` implementation, e.g.:
+      ```
+      org.opensearch.sample.SampleResourcePlugin
+      ```
+---
+
+## **3. Feature Flag**
+This feature is controlled by the following flag:
+
+- **Feature flag:** `plugins.security.resource_sharing.enabled`
+- **Default value:** `true`
+- **How to disable?** Set the flag to `false` in the opensearch configuration:
+  ```yaml
+  plugins.security.resource_sharing.enabled: false
+  ```
+
+---
+
+## **4. Declaring a Resource Plugin and Using the Client for Access Control**
+### **Declaring a Plugin as a Resource Plugin**
+To integrate with the security plugin, your plugin must:
+1. Extend `ResourceSharingExtension` and implement required methods.
+2. Implement the `Resource` interface for resource declaration.
+3. Implement a resource parser to extract resource details.
+
+[`opensearch-resource-sharing-spi` README.md](./spi/README.md) is a great resource to learn more about the components of SPI and how to set up.
+
+Tip: Refer to the `org.opensearch.sample.SampleResourcePlugin` class to understand the setup in further detail.
+
+Example usage:
+```java
+
+public class SampleResourcePlugin extends Plugin implements SystemIndexPlugin, ResourceSharingExtension {
+
+    // override any required methods
+
+    @Override
+    public Collection<SystemIndexDescriptor> getSystemIndexDescriptors(Settings settings) {
+        final SystemIndexDescriptor systemIndexDescriptor = new SystemIndexDescriptor(RESOURCE_INDEX_NAME, "Sample index with resources");
+        return Collections.singletonList(systemIndexDescriptor);
+    }
+
+    @Override
+    public String getResourceType() {
+        return SampleResource.class.getCanonicalName();
+    }
+
+    @Override
+    public String getResourceIndex() {
+        return RESOURCE_INDEX_NAME;
+    }
+
+    @Override
+    public ResourceParser<SampleResource> getResourceParser() {
+        return new SampleResourceParser();
+    }
+}
+```
+
+
+### **Calling Access Control Methods from the ResourceSharingClient Client**
+Plugins must **declare a dependency** on `opensearch-security-client` and use it to call access control methods.
+The client provides **four access control methods** for plugins. For detailed usage and implementation, refer to the [`opensearch-security-client` README.md](./client/README.md)
+
+
+Tip: Refer to the `org.opensearch.sample.resource.client.ResourceSharingClientAccessor` class to understand the client setup in further detail.
+
+Example usage:
+```java
+ @Override
+void doExecute(Task task, ShareResourceRequest request, ActionListener<ShareResourceResponse> listener) {
+    if (request.getResourceId() == null || request.getResourceId().isEmpty()) {
+        listener.onFailure(new IllegalArgumentException("Resource ID cannot be null or empty"));
+        return;
+    }
+
+    ResourceSharingClient resourceSharingClient = ResourceSharingClientAccessor.getResourceSharingClient(nodeClient, settings);
+    resourceSharingClient.shareResource(
+            request.getResourceId(),
+            RESOURCE_INDEX_NAME,
+            request.getShareWith(),
+            ActionListener.wrap(sharing -> {
+                ShareResourceResponse response = new ShareResourceResponse(sharing.getShareWith());
+                listener.onResponse(response);
+            }, listener::onFailure)
+    );
+}
+```
+
+
+---
+
+## **5. What are Scopes?**
+
+This feature introduces a new **sharing mechanism** called **scopes**. Scopes define **the level of access** granted to users for a resource. They are **defined and maintained by plugins**, and the security plugin does **not** interpret or enforce their specific meanings. This approach gives plugins the **flexibility** to define scope names and behaviors based on their use case.
+
+Each plugin must **document its scope definitions** so that users understand the **sharing semantics** and how different scopes affect access control.
+
+Scopes enable **granular access control**, allowing resources to be shared with **customized permission levels**, making the system more flexible and adaptable to different use cases.
+
+### **Common Scopes for Plugins to declare**
+| Scope        | Description                                         |
+|-------------|-----------------------------------------------------|
+| `PUBLIC`    | The resource is accessible to all users.            |
+| `READ_ONLY` | Users can view but not modify the resource.         |
+| `READ_WRITE` | Users can view and modify the resource.             |
+
+By default, all resources are private and only visible to the owner and super-admins. Resources become accessible to others only when explicitly shared.
+
+SPI provides you an interface, with two default scopes `PUBLIC` and `RESTRICTED`, which can be extended to introduce more plugin-specific values.
+
+### **Using Scopes in API Design**
+- APIs should be logically paired with correct scopes.
+  - Example, **GET APIs** should be logically paired with **`READ_ONLY`**, **`READ_WRITE`**, or **`PUBLIC`** scopes. When verifying access, these scopes must be **passed to the security plugin** via the `ResourceSharingNodeClient` to determine whether a user has the required permissions.
+
+
+---
+
+## **6. Restrictions**
+1. At present, **only resource owners can share/revoke access** to their own resources.
+    - **Admins** can manage access for any resource.
+2. **Resources must be stored in a system index**, and system index protection **must be enabled**.
+    - **Disabling system index protection** allows users to access resources **directly** if they have relevant index permissions.
+3. **This feature works on top of existing index-level authorization** and does not replace it.
+4. **A user must already have index access** in order to access the resource.
+
+---
+
+## **7. REST APIs Introduced by the Security Plugin**
+
+In addition to client methods, the **Security Plugin** introduces new **REST APIs** for managing resource access when the feature is enabled. These APIs allow users to **verify, grant, revoke, and list access** to resources.
+
+---

+
+### **4. List Accessible Resources**
+- **Endpoint:**
+  ```
+  GET /_plugins/_security/resources/list/{resource_index}
+  ```
+- **Description:**
+  Retrieves a list of **resources that the current user has access to** within the specified `{resource_index}`.
+
+#### **Response:**
+Returns an array of accessible resources.
+```json
+{
+  "resources": [
+    {
+      "name": "my-resource-name",
+      "description": "My resource description.",
+      "attributes": {
+        "type": "model"
+      }
+    }
+  ]
+}
+```
+*This is an example resource. Actual structure will vary based on your configuration.*
+
+---
+
+## **Additional Notes**
+- **Feature Flag:** These APIs are available only when `plugins.security.resource_sharing.enabled` is set to `true` in the configuration.
+- **Index Restrictions:** Resources must be stored in **system indices**, and **system index protection** must be enabled to prevent unauthorized access.
+- **Scopes Flexibility:** The `share_with` field allows defining **custom access scopes** as per plugin requirements.
+
+---
+
+## **8. Best Practices**
+### **For Plugin Developers**
+- **Declare resources properly** in the `ResourceSharingExtension`.
+- **Use the security client** instead of direct index queries to check access.
+- **Implement a resource parser** to ensure correct resource extraction.
+
+### **For Users & Admins**
+- **Keep system index protection enabled** for better security.
+- **Grant access only when necessary** to limit exposure.
+- **Regularly audit resource access**.
+
+---
+
+## **Conclusion**
+The **Resource Sharing and Access Control** feature enhances OpenSearch security by introducing an **additional layer of fine-grained access management** for plugin-defined resources. While **Fine-Grained Access Control (FGAC)** is already enabled, this feature provides **even more granular control** specifically for **resource-level access** within plugins.
+
+By implementing the **Service Provider Interface (SPI)**, utilizing the **security client**, and following **best practices**, developers can seamlessly integrate this feature into their plugins to enforce controlled resource sharing and access management.
+
+For detailed implementation and examples, refer to the **[sample plugin](./sample-resource-plugin)** included in the security plugin repository.

+
+## **Available Java APIs**
+
+The **`ResourceSharingClient`** provides **four Java APIs** for **resource access control**, enabling plugins to **verify, share, revoke, and list** resources.
+
+📌 **Package Location:**
+🔗 [`org.opensearch.security.client.resources.ResourceSharingClient`](../client/src/main/java/org/opensearch/security/client/resources/ResourceSharingClient.java)
+
+---
+
+### **API Usage Examples**
+Below are examples demonstrating how to use each API effectively.
+
+---
+
+### **1. `verifyResourceAccess`**
+🔍 **Checks if the current user has access to a resource** based on predefined **scopes**.
+
+#### **Method Signature:**
+```java
+void verifyResourceAccess(String resourceId, String resourceIndex, Set<String> scopes, ActionListener<Boolean> listener);
+```
+
+#### **Example Usage:**
+```java
+Set<String> scopes = Set.of("READ_ONLY");
+resourceSharingClient.verifyResourceAccess(
+    "resource-123",
+    "resource_index",
+    scopes,
+    ActionListener.wrap(isAuthorized -> {
+        if (isAuthorized) {
+            System.out.println("User has access to the resource.");
+        } else {
+            System.out.println("Access denied.");
+        }
+    }, e -> {
+        System.err.println("Failed to verify access: " + e.getMessage());
+    })
+);
+```
+> ✅ **Use Case:** Before performing operations like **deletion or modifications**, ensure the user has the right permissions.
+
+---
+
+### **2. `shareResource`**
+🔄 **Grants access to a resource** for specific users, roles, or backend roles.
+
+#### **Method Signature:**
+```java
+void shareResource(String resourceId, String resourceIndex, Map<String, Object> shareWith, ActionListener<ResourceSharing> listener);
+```
+
+#### **Example Usage:**
+```java
+Map<String, Object> shareWith = Map.of(
+    "users", List.of("user_1", "user_2"),
+    "roles", List.of("admin_role"),
+    "backend_roles", List.of("backend_group")
+);
+
+resourceSharingClient.shareResource(
+    "resource-123",
+    "resource_index",
+    shareWith,
+    ActionListener.wrap(response -> {
+        System.out.println("Resource successfully shared with: " + shareWith);
+    }, e -> {
+        System.err.println("Failed to share resource: " + e.getMessage());
+    })
+);
+```
+> ✅ **Use Case:** Used when an **owner/admin wants to share a resource** with specific users or groups.
+
+---
+
+### **3. `revokeResourceAccess`**
+🚫 **Removes access permissions** for specified users, roles, or backend roles.
+
+#### **Method Signature:**
+```java
+void revokeResourceAccess(String resourceId, String resourceIndex, Map<String, Object> entitiesToRevoke, Set<String> scopes, ActionListener<ResourceSharing> listener);
+```
+
+#### **Example Usage:**
+```java
+Map<String, Object> entitiesToRevoke = Map.of(
+    "users", List.of("user_2"),
+    "roles", List.of("viewer_role")
+);
+Set<String> scopesToRevoke = Set.of("READ_ONLY");
+
+resourceSharingClient.revokeResourceAccess(
+    "resource-123",
+    "resource_index",
+    entitiesToRevoke,
+    scopesToRevoke,
+    ActionListener.wrap(response -> {
+        System.out.println("Resource access successfully revoked for: " + entitiesToRevoke);
+    }, e -> {
+        System.err.println("Failed to revoke access: " + e.getMessage());
+    })
+);
+```
+> ✅ **Use Case:** When a user no longer needs access to a **resource**, their permissions can be revoked.
+
+---
+
+### **4. `listAllAccessibleResources`**
+📜 **Retrieves all resources the current user has access to.**
+
+#### **Method Signature:**
+```java
+void listAllAccessibleResources(String resourceIndex, ActionListener<Set<? extends Resource>> listener);
+```
+
+#### **Example Usage:**
+```java
+resourceSharingClient.listAllAccessibleResources(
+    "resource_index",
+    ActionListener.wrap(resources -> {
+        for (Resource resource : resources) {
+            System.out.println("Accessible Resource: " + resource.getId());
+        }
+    }, e -> {
+        System.err.println("Failed to list accessible resources: " + e.getMessage());
+    })
+);
+```
+> ✅ **Use Case:** Helps a user identify **which resources they can interact with**.
+
+---
+
+## **Conclusion**
+These APIs provide essential methods for **fine-grained resource access control**, enabling:
+
+✔ **Verification** of resource access.
+✔ **Granting and revoking** access dynamically.
+✔ **Retrieval** of all accessible resources.
+
+For further details, refer to the [`ResourceSharingClient` Java class](../client/src/main/java/org/opensearch/security/client/resources/ResourceSharingClient.java). 🚀

-Checklist for resource plugin:
-1. Add a dependency on `opensearch-security-client` and `opensearch-resource-sharing-spi` in build.gradle.
-2. Under `src/main/resources` folder of the plugin, locate or create a folder `META-INF/services`and in the services folder, declare a file named `org.opensearch.security.spi.resources.ResourceSharingExtension`. Edit that file to add single line containing classpath of your plugin, e.g `org.opensearch.sample.SampleResourcePlugin`. This is required to utilize Java's Service Provider Interface mechanism.
-3. Declare a resource class and implement `Resource` class from SPI.
-4. Implement a `ResourceParser`.
-5. Implement `ResourceSharingExtension` interface in the plugin declaration class, and implement required methods (as shown above). Ensure that resource index is marked as a system index.
-6. Create a client accessor that will instantiate `ResourceSharingNodeClient`.
-7. Use the methods provided by `ResourceSharingNodeClient` to implement resource access-control.
+---
+
+## **Checklist for Implementing a Resource Plugin**
+
+To properly integrate with the **Resource Sharing and Access Control SPI**, follow these steps:
+
+### **1. Add Required Dependencies**
+Include **`opensearch-security-client`** and **`opensearch-resource-sharing-spi`** in your **`build.gradle`** file.
+Example:
+```gradle
+dependencies {
+    implementation 'org.opensearch:opensearch-security-client:VERSION'
+    implementation 'org.opensearch:opensearch-resource-sharing-spi:VERSION'
+}
+```
+
+---
+
+### **2. Register the Plugin Using the Java SPI Mechanism**
+- Navigate to your plugin's `src/main/resources` folder.
+- Locate or create the `META-INF/services` directory.
+- Inside `META-INF/services`, create a file named:
+  ```
+  org.opensearch.security.spi.resources.ResourceSharingExtension
+  ```
+- Edit the file and add a **single line** containing the **fully qualified class name** of your plugin implementation.
+  Example:
+  ```
+  org.opensearch.sample.SampleResourcePlugin
+  ```
+  > ✅ This step ensures that OpenSearch **dynamically loads your plugin** as a resource-sharing extension.
+
+---
+
+### **3. Declare a Resource Class**
+Each plugin must define a **resource class** that implements the `Resource` interface.
+Example:
+```java
+public class SampleResource implements Resource {
+    private String id;
+    private String owner;
+
+    // Constructor, getters, setters, etc.
+
+    @Override
+    public String getResourceId() {
+        return id;
+    }
+}
+```
+
+---
+
+### **4. Implement a Resource Parser**
+A **`ResourceParser`** is required to convert **resource data** from OpenSearch indices.
+Example:
+```java
+public class SampleResourceParser implements ResourceParser<SampleResource> {
+    @Override
+    public SampleResource parseXContent(XContentParser parser) throws IOException {
+        return SampleResource.fromXContent(parser);
+    }
+}
+```
+
+---
+
+### **5. Implement the `ResourceSharingExtension` Interface**
+Ensure that your **plugin declaration class** implements `ResourceSharingExtension` and provides **all required methods**.
+
+✅ **Important:** Mark the resource **index as a system index** to enforce security protections.
+
+---
+
+### **6. Create a Client Accessor**
+A **singleton accessor** should be created to manage the `ResourceSharingNodeClient`.
+Example:
+```java
+public class ResourceSharingClientAccessor {
+    private static ResourceSharingNodeClient INSTANCE;
+
+    private ResourceSharingClientAccessor() {}
+
+    public static ResourceSharingNodeClient getResourceSharingClient(NodeClient nodeClient, Settings settings) {
+        if (INSTANCE == null) {
+            INSTANCE = new ResourceSharingNodeClient(nodeClient, settings);
+        }
+        return INSTANCE;
+    }
+}
+```
+
+---
+
+### **7. Utilize `ResourceSharingNodeClient` for Access Control**
+Use the **client API methods** to manage resource sharing.
+
+#### **Example: Verifying Resource Access**
+```java
+Set<String> scopes = Set.of("READ_ONLY");
+resourceSharingClient.verifyResourceAccess(
+    "resource-123",
+    "resource_index",
+    scopes,
+    ActionListener.wrap(isAuthorized -> {
+        if (isAuthorized) {
+            System.out.println("User has access to the resource.");
+        } else {
+            System.out.println("Access denied.");
+        }
+    }, e -> {
+        System.err.println("Failed to verify access: " + e.getMessage());
+    })
+);
+```

-## **6. Restrictions**
+## **6. User Setup**
+
+To enable users to interact with the **Resource Sharing and Access Control** feature, they must be assigned the appropriate cluster permissions along with resource-specific access.
+
+### **Required Cluster Permissions**
+Users must be assigned the following **cluster permissions** in `roles.yml`:
+
+- **`cluster:admin/security/resource_access`** → Required to evaluate resource permissions.
+- **Plugin-specific cluster permissions** → Required to interact with the plugin’s APIs.
+
+#### **Example Role Configurations**
+```yaml
+sample_full_access:
+  cluster_permissions:
+    - 'cluster:admin/security/resource_access'
+    - 'cluster:admin/sample-resource-plugin/*'
+
+sample_read_access:
+  cluster_permissions:
+    - 'cluster:admin/security/resource_access'
+    - 'cluster:admin/sample-resource-plugin/get'
+```
+
+
+### **User Access Rules**
+1. **Users must have the required cluster permissions**
+    - Even if a resource is shared with a user, they **cannot access it** unless they have the **plugin’s cluster permissions**.
+
+2. **Granting plugin API permissions does not automatically grant resource access**
+    - A resource must be **explicitly shared** with the user.
+    - **Or, the user must be the resource owner.**
+
+3. **No index permissions are required**
+    - Access control is **handled at the cluster level**.
+    - The `.opensearch_resource_sharing` index and the resource indices are protected under system index security.
+
+
+### **Summary**
+| **Requirement** | **Description**                                                                       |
+|---------------|---------------------------------------------------------------------------------------|
+| **Cluster Permission** | `cluster:admin/security/resource_access` required for resource evaluation.            |
+| **Plugin API Permissions** | Users must also have relevant plugin API cluster permissions.                         |
+| **Resource Sharing** | Access is granted only if the resource is shared with the user or they are the owner. |
+| **No Index Permissions Needed** | The `.opensearch_resource_sharing` index and resource indices are system-protected.   |
+
+
+---
+
+## **7. Restrictions**
 1. At present, **only resource owners can share/revoke access** to their own resources.
-    - **Admins** can manage access for any resource.
+    - **Super admins** can manage access for any resource.
 2. **Resources must be stored in a system index**, and system index protection **must be enabled**.
     - **Disabling system index protection** allows users to access resources **directly** if they have relevant index permissions.
-3. **This feature works on top of existing index-level authorization** and does not replace it.
-4. **A user must already have index access** in order to access the resource.

+## Installation
+
+1. Clone the repository:
+   ```bash
+   git clone git@github.com:opensearch-project/security.git
+   ```
+
+2. Navigate to the project directory:
+   ```bash
+   cd sample-resource-plugin
+   ```
+
+3. Build and deploy the plugin:
+   ```bash
+   $ ./gradlew clean build -x test -x integrationTest -x spotbugsIntegrationTest
+   $ ./bin/opensearch-plugin install file: <path-to-this-plugin>/sample-resource-plugin/build/distributions/opensearch-sample-resource-plugin-<version-qualifier>.zip
+   ```
+
+
+## User setup:
+1. **New Security Permission Requirement**
+    - Users need **`cluster:admin/security/resource_access`** in their role to **interact with shared resources**.
+    - This applies **in addition to** any plugin-specific cluster permissions.
+
+2. **No Index-Level Permissions Required**
+    - **Resource access is controlled at the cluster level**.
+    - Users **do not** need explicit index-level permissions to access shared resources.
+
+3. **Sample Role Configurations**
+    - Below are **two sample roles** demonstrating how to configure permissions in `roles.yml`:
+
+    ```yaml
+    sample_full_access:
+     cluster_permissions:
+       - 'cluster:admin/security/resource_access'
+       - 'cluster:admin/sample-resource-plugin/*'
+
+    sample_read_access:
+     cluster_permissions:
+       - 'cluster:admin/security/resource_access'
+       - 'cluster:admin/sample-resource-plugin/get'
+    ```
+
+4. **Interaction Rules**
+    - If a **user is not the resource owner**, they must:
+        - Be assigned **a role with `sample_read_access`** permissions.
+        - **Have the resource shared with them** via the resource-sharing API.
+    - A user **without** the necessary `sample-resource-plugin` cluster permissions:
+        - **Cannot access the resource**, even if it is shared with them.
+    - A user **with `sample-resource-plugin` permissions** but **without a shared resource**:
+        - **Cannot access the resource**, since resource-level access control applies.

 ### **Plugin Implementation Requirements**
 Each plugin must:
+- **Declare a dependency** on `opensearch-security-client` package:
+```build.gradle
+implementation group: 'org.opensearch', name:'opensearch-security-client', version: "${opensearch_build}"
+```
+- **Extend** `opensearch-security` plugin with optional flag:
+```build.gradle
+opensearchplugin {
+    name '<your-plugin>'
+    description '<description>'
+    classname '<your-classpath>'
+    extendedPlugins = ['opensearch-security;optional=true', <any-other-extensions>]
+}
+```
 - **Implement** the `ResourceSharingExtension` class.
 - **Ensure** that its declared resources implement the `Resource` interface.
 - **Provide a resource parser**, which the security plugin uses to extract resource details from the resource index.
