+
+## Getting Started
+
+A `Vagrantfile` has been provided in order to make this code more convenient to
+run. To get started via `Vagrant`, you'll need:
+
+* A working `Vagrant` environment
+* A `git checkout` of this repository
+* A copy of `GeoLite2-Country.mmdb` in the root of this repository
+
+## Building Your Vagrant VM
+
+After you have checked out this repository and added a `GeoLite2-Country.mmdb` to
+the root directory of the repository, run this command from the root directory.
+
+```bash
+vagrant up
+```
+
+## Logging in to Your VM
+
+This will build your Vagrant VM, build your `Go` code and also run the example
+code for you. To log in to your container, run this command:.
+
+```bash
+vagrant ssh
+cd /vagrant
+```
+
+## Inspecting Your Database
+
+Once you have logged in, you can test out your freshly created database:
+
+```bash
+mmdbinspect -db GeoLite2-Country.mmdb \
+-db GeoLite2-Country-with-Department-Data.mmdb \
+56.0.0.1 56.1.0.0/24 56.2.0.54 56.3.0.1 | less
+```
+
+## Refactoring Your Code
+
+You can now freely edit the code outside of the Vagrant VM and re-run it from
+inside the VM.
+
+### Re-creating the database
+
+After you have edited the files, log in to your VM using the instructions above
+and run the following code:
+
+```bash
+go build && ./mmdb-from-go-blogpost
+```

 And that's it! You've now built yourself a GeoLite2 Country MMDB file enriched with custom data.
 
+### Using Docker or Vagrant
+
+The code repository comes with a [Dockerfile](https://github.com/maxmind/mmdb-from-go-blogpost/blob/master/Dockerfile) and a [Vagrantfile](https://github.com/maxmind/mmdb-from-go-blogpost/blob/master/Vagrantfile) included. If you'd like to begin work in an environment which has all of the necessary software dependencies pre-installed, see our documentation for getting started with [Docker](https://github.com/maxmind/mmdb-from-go-blogpost/blob/master/README-Docker.md) and [Vagrant](https://github.com/maxmind/mmdb-from-go-blogpost/blob/master/README-Vagrant.md).
