+# Docker Compose V1 + V2 registry
+
+This compose configuration will setup a v1 and v2 registry behind an nginx
+proxy. By default the combined registry may be accessed at localhost:5000.
+This registry does not support pushing images to v2 and pull from v1. Clients
+from before 1.6 will be configured to use the v1 registry, and newer clients
+will use the v2 registry.
+
+## Prerequisites
+Install [docker-compose](https://github.com/docker/compose)
+
+## How to run
+```
+$ docker-compose up
+```
+
+## How to push images
+From a local project directory with Dockerfile
+```
+$ docker build -t localhost:5000/myimage .
+$ docker push localhost:5000/myimage
+```
+
