 # Envoy Binaries
+
+For some platforms, envoy is only distributed via docker images.
+
+This repo contains: 
+ - a utility to extract envoy binaries from upstream container images
+ - releases to house the envoy binary assets in an easily accessible place
+
+# Releasing
+
+When a release tag is created, the envoy binaries will be automatically extracted from the matching `envoyproxy/envoy` image tag and uploaded to the release.
