 ## Settings
@@ -76,8 +76,8 @@ Most of settings are obvious and easy to understand, but there are some settings
 - **Run User**: keep it as default value `git` because `finalize.sh` already setup a user with name `git`.
 - **Domain**: fill in with Docker container IP (e.g. `192.168.99.100`). But if you want to access your Gogs instance from a different physical machine, please fill in with the hostname or IP address of the Docker host machine.
 - **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. **Builtin SSH server is not recommended inside Docker Container**
-- **HTTP Port**: Use port you want Gogs to listen on inside Docker container. For example, your Gogs listens on `3000` inside Docker, **and** you expose it by `10080:3000`, but you still use `3000` for this value.
-- **Application URL**: Use combination of **Domain** and **exposed HTTP Port** values (e.g. `http://192.168.99.100:10080/`).
