 Most of settings are obvious and easy to understand, but there are some settings can be confusing by running Gogs inside Docker:
 
-- Repository Root Path: keep it as default value `/home/git/gogs-repositories` because `start.sh` already made a symbolic link for you.
+- **Repository Root Path**: keep it as default value `/home/git/gogs-repositories` because `start.sh` already made a symbolic link for you.
-- Run User: keep it as default value `git` because `start.sh` already setup a user with name `git`.
+- **Run User**: keep it as default value `git` because `start.sh` already setup a user with name `git`.

+- **Domain**: fill in with Docker container IP(e.g. `192.168.99.100`).
-- SSH Port: Use the exposed port from Docker container. For example, your SSH server listens on `22` inside Docker, but you expose it by `10022:22`, then use `10022` for this value.
+- **SSH Port**: Use the exposed port from Docker container. For example, your SSH server listens on `22` inside Docker, but you expose it by `10022:22`, then use `10022` for this value.
-- HTTP Port: Use the exposed port from Docker container. For example, your Gogs listens on `3000` inside Docker, but you expose it by `10080:3000`, then use `10080` for this value.
