 # GitHub Action to deploy an MkDocs site to GitHub Pages

 This GitHub action will deploy your [MkDocs site](https://www.mkdocs.org/) as [GitHub Pages](https://pages.github.com/), using the [Material](https://github.com/squidfunk/mkdocs-material) theme. It assumes that an `mkdocs.yml` file is present in the top-level directory and the source files (Markdown, etc.) are in the `docs/` folder. You can use [mhausenblas/mkdocs-template](https://github.com/mhausenblas/mkdocs-template) as a template.

 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.
 
+You may need to give the `GITHUB_TOKEN` write permission. Go to your repository's **Settings > Actions > General > Workflow Permissions** and select **Read and write permissions**.
+
 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.
+
+### Custom repository
+
+In case you want to push to another repository than origin define `GITHUB_ORIGIN`. Needs building with `PERSONAL_TOKEN`.

 ### 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.

 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.
