 ## Create a chart repository
 A _chart repository_ is an HTTP server that houses one or more packaged charts. When you're ready to share your charts, the preferred mechanism is a chart repository. You can contribute to the official helm chart repository or create your own. Here we'll talk about creating your own chart repository.
 
-Because a chart repository can be any HTTP server that can serve YAML and tar files and can answer GET requests, you have a plethora of options when it comes down to hosting your own chart repository. For example, you can use a Google Cloud Storage(GCS) bucket, Amazon S3 bucket, or even create your own web server.

 ### The chart repository structure
 A chart repository consists of packaged charts and a special file called `index.yaml` which contains an index of all of the charts in the repository. A chart repository has a flat structure. Given a repository URL, you should be able to download a chart via a GET request to `URL/chartname-version.tgz`.

+##### Github Pages example
+
+In a similar way you can create charts repository using Github Pages.
+
+The first step will be to **create your gh-pages branch**.
+You can do that localy as.
+
+```
+$ git checkout -b [name_of_your_new_branch]
+```
+
+Or via web browser using **Branch** button on your Github repository:

+![Create Github Pages branch](images/create-a-gh-page-button.png)
+
+Next, you'll want to make sure your **gh-pages branch** is set as Github Pages, click on your repo **Settings** and scroll down to **Github pages** section and set as per below:
+
+![Create Github Pages branch](images/set-a-gh-page.png)
+
+By default **Source** usually gets set to **gh-pages branch**, if not do so select it.
+
+You can use a **custom domain** there if you wish so.
+
+And check that **Enforce HTTPS** is ticked, so the **HTTPS** will be used when charts are served.
+
+In such setup you can use **master branch** to store your charts code, and **gh-pages branch** as charts repository, e.g.: `https://my-repo-name.github.io/charts`.

 ## Store charts in your chart repository
 Now that you have a chart repository, let's upload a chart and an index file to the repository.
 Charts in a chart repository must be packaged (`helm package chart-name/`) and versioned correctly (following [SemVer 2](https://semver.org/) guidelines).
