 For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
 Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
 
+## User / Group Identifiers
+
+When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.
+
+Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

+In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:

+```bash
+  $ id username
