- A bug in `entry` caused the script to not change into the directory correctly.
This was corrected by marking the script as bash rather than sh.
- `install.sh` now stops a running service before updating
- `docker-compose.yml` now assigns a consistent container name for the app
- `docker-compose.yml` now uses environment variables or a `.env` file to
assign container name and port mappings if available
- updated readme file with better instructions
