 By default, GitHub Pages uses Jekyll (a ruby based static site generator),
 but you can also publish any generated files provided you have an `index.html` file in the root of a branch called
 `gh-pages` or `master`. In addition you can publish from a `docs` directory in your repository. That branch name can

-i.e., if you want to publish to a GitHub-provided web service under the `github.io` domain, you can **only** use the
-`master` branch of your repository, as explained

 We can use any continuous integration (CI) server to build and deploy our site. For example:
 
- * [Github Actions](https://github.com/shalzz/zola-deploy-action)
+ * [Github Actions](#github-actions)
  * [Travis CI](#travis-ci)
 
+## Github Actions
+
+Using *Github Actions* for the deployment of your Zola-Page on Github-Pages is pretty easy. You basically need three things:
+
+1. A *Personal access token* to give the *Github Action* the permission to push into your repository.
+2. Create the *Github Action*.
+3. Check the *Github Pages* section in repository settings.
+
+Let's start with the token.
+
+For creating the token either click on [here](https://github.com/settings/tokens) or go to Settings > Developer Settings > Personal access tokens. Under the *Select Scopes* section, give it *repo* permissions and click *Generate token*. Then copy the token, navigate to your repository and add in the Settings tab the *Secret* `TOKEN` and paste your token in it.
+
+Next we need to create the *Github Action*. Here we can make use of the [zola-deploy-action](https://github.com/shalzz/zola-deploy-action). Go to the *Actions* tab of your repository, click on *set up a workflow yourself* to get a blank workflow file. Copy the following script into it and commit it afterwards.
+
+```yaml
+# On every push this script is executed
+on: push
+name: Build and deploy GH Pages
+jobs:
+  build:
+    name: shalzz/zola-deploy-action
+    runs-on: ubuntu-latest
+    steps:
+    # Checkout
+    - uses: actions/checkout@master
+    # Build & deploy
+    - name: shalzz/zola-deploy-action
+      uses: shalzz/zola-deploy-action@v0.12.0
+      env:
+        # Target branch
+        PAGES_BRANCH: gh-pages
+        # Provide personal access token
+        TOKEN: ${{ secrets.TOKEN }}
+```
+
+This script is pretty simple, because the [zola-deploy-action](https://github.com/shalzz/zola-deploy-action) is doing everything for you. You just need to provide some details. For more configuration options check out the [README](https://github.com/shalzz/zola-deploy-action/blob/master/README.md).
+
+By commiting the action your first build is triggered. Wait until it's finished, then you should see in your repository a new branch *gh-pages* with the compiled *Zola* page in it.
+
+Finally we need to check the *Github Pages* section of the repository settings. Click on the *Settings* tab and scroll down to the *Github Pages* section. Check if the source is set to *gh-pages* branch and the directory is */ (root)*. You should also see your *Github Pages* link.
+
+There you can also configure a *custom domain* and *Enforce HTTPS* mode. Before configuring a *custom domains*, please check out [this](https://github.com/shalzz/zola-deploy-action/blob/master/README.md#custom-domain).

 ## Travis CI
 
 We are going to use [Travis CI](https://travis-ci.org) to automatically publish the site. If you are not using Travis
