 ### Building with `PERSONAL_TOKEN`
 
-[Generate a personal access token (scope `repo`)](https://github.com/settings/tokens) and [create a secret](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets) in your repository settings with the name `PERSONAL_TOKEN` and the value of the token generated.

 ### Building with `GITHUB_TOKEN`
 
-This action supports building and deploying with a `GITHUB_TOKEN`. This token is automatically generated by Github Actions when a workflow runs so it is convenient.

-It is more **secure** than a personal token, since you never actually see the value of the `GITHUB_TOKEN` and also the `GITHUB_TOKEN` is scoped to only work for a **single** repo.

-Note that for this approach, Github Pages will be enabled in Settings but you will _not_ have a URL displayed or environment tab yet. So change the Github Pages settings to another target and then back again to `gh-pages` (if that is your branch to serve) - then you will see a URL. This step is only needed on the _first_ deploy and no action is needed later on.

 ### Alternative `GITHUB_DOMAIN`
 
-In case this action should be used in a Github Enterprise environment you can overwrite the `github.com` domain with your corresponding Github Enterprise domain name by specifying the `GITHUB_DOMAIN` environment variable.

+### Building with `CUSTOM_DOMAIN` for Github Pages
 
-MkDocs can be deployed to github pages using a custom domain, if you populate a `CUSTOM_DOMAIN` environment variable. This will generate a CNAME file, which will be placed inside the `/docs` folder.
+- MkDocs can be deployed to github pages using a custom domain, if you populate a `CUSTOM_DOMAIN` environment variable. This will generate a CNAME file, which by default will be placed inside the `/docs` folder.
+- Using the ``CUSTOM_DOCS`` environment variable will change this folder, and should match the ``docs_dir`` in your ``mkdocs.yml``file.

 ### Custom File Pathing of Mkdocs file
 
-This action supports deployment of mkdocs with different file path , if you populate a `CONFIG_FILE` environment variable. This is important if you have mkdocs file in another folder such as if you have `mkdocs.yml` in a path `docs/mkdocs.yml`. Without populating this, the deployment assumes that `mkdocs.yml` is on the root folder.

 ## Installing extra packages
 
-Some Python packages require C bindings. These packages can be installed using the `EXTRA_PACKAGES` variable. The `EXTRA_PACKAGES` variable will be passed to the `apk add` command of Alpine Linux before running `pip install` to install the Python packages.

 ## Installing mkdocs plugins
 
-If you use some mkdocs plugins like [`codeinclude`](https://github.com/rnorth/mkdocs-codeinclude-plugin) then you need to define it as dependency in the typical python way with a `requirements.txt` file. In the sample above you need to add the line `mkdocs-codeinclude-plugin`. Then you need to link the file using the `REQUIREMENTS` variable.
