 The "custom" directory may not be obvious in Docker environment. The `/var/gogs/gogs` (in the host) and `/data/gogs` (in the container) is already the "custom" directory and you do not need to create another layer but directly edit corresponding files under this directory.
 
-### Volume With Data Container

-If you're more comfortable with mounting data to a data container, the commands you execute at the first time will look like as follows:
-
-```sh
-# Create data container
-docker run --name=gogs-data --entrypoint /bin/true gogs/gogs

-# Use `docker run` for the first time.
-docker run --name=gogs --volumes-from gogs-data -p 10022:22 -p 10880:3000 gogs/gogs

 - **Run User**: keep it as default value `git` because `finalize.sh` already setup a user with name `git`.
