 And that's it! Read the accompanying [blog post](https://medium.com/@rdsubhas/docker-image-with-tor-privoxy-and-a-process-manager-under-15-mb-c9e344111b61) for more details.
 
+To customize the configuration, add volume mount like: `-v $PWD/torrc:/etc/tor/torrc:ro` (see default [sample `torrc` file](https://gitweb.torproject.org/tor.git/plain/src/config/torrc.sample.in)). You may also want to mount what you've set a Tor `DataDirectory` (see [Tor Manual](https://www.torproject.org/docs/tor-manual.html.en#_files) for details of each sub-directory) to avoid losing caches and identities when you restart your container.

 ## Known Issues
 
 * When running in interactive mode, pressing Ctrl+C doesn't cleanly exit. For now, run it in detached mode (`-d`). Calling `docker stop` cleanly exits though.
