+Default is `false`. When set to `true`, GitHub OAuth App Authentication will be performed to verify users' access to the dashboard. For this, a GitHub App must be registered and installed in the enterprise/org. See [Github App Registration](DEPLOYMENT.md#github-app-registration) for the steps to follow.
 
 Variables required for GitHub Auth are:
-1. `NUXT_OAUTH_GITHUB_CLIENT_ID` - client ID of the GitHub App registered and installed in the enterprise/org with permissions listed in [NUXT_GITHUB_TOKEN](#NUXT_GITHUB_TOKEN).

 2. `NUXT_OAUTH_GITHUB_CLIENT_SECRET` - client secret of the GitHub App.
 3. [Optional] `NUXT_OAUTH_GITHUB_CLIENT_SCOPE` for scope requests when using OAuth App instead of GitHub App. See [Github docs](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/differences-between-github-apps-and-oauth-apps) for details.

 Solution supports HTTP Proxy settings when running in corporate environment. Simple set `HTTP_PROXY` environment variable.
 
 For custom CA use environment variable `CUSTOM_CA_PATH` to load the certificate into proxy agent options.
 
+#### NITRO_PORT
+
+Default is `80` in the [Dockerfile](Dockerfile). It defines the port number that Nitro (Nuxt’s server engine) will listen on.
+
+For example, it should be set to a number between 1024 and 49151 if the application is run as a non-root user.
