 While experimenting with various docker containers from the Hub, I realized that I'd started several containers with complex options for volumes, ports, environment variables, etc. and there was no way I could remember all those commands without referencing the Hub page for each image if I needed to delete and re-create the container (for updates, or if something broke).
 
 With this tool, I can easily generate docker-compose files for managing the containers that I've set up manually.

+## Docker Usage
+
+Build container by running:
+
+    docker build -t docker-autocompose .

+Use the new image to generate a docker-compose file from a running container:
+
+     docker run -v /var/run/docker.sock:/var/run/docker.sock docker-autocompose $container-id
