+## How to unpublish a Docusaurus website
+
+To safely unpublish a docusaurus website, we need to undo or stop the steps taken by Flowzone to publish the Cloudflare Pages website. This can be done by following the steps below:
+
+1. Create a pull request to amend `flowzone.yml` file. Delete the `cloudflare_website` property. Once the pull request is merged, the GitHub action will stop running and the website will not be updated on Cloudflare Pages. 
+2. To remove the content from Cloudflare Pages, please navigate to `Cloudflare Pages & Workers` page and delete the project from the Cloudflare Pages dashboard.
+3. On removing the entry, Cloudflare will prompt you to also delete the DNS entry for the Cloudflare Page. Please confirm the deletion of the DNS entry as well.
+4. To prevent squatting on the Cloudflare Page, please create a new empty project of the same name to reclaim that domian. This will also help in preventing any future conflicts with the same domain name.
+5. (Optional) If needed, redirect the DNS entry to back to [balena.io](balena.io) or a new target to not lose the traffic or break the user experience. If you need help with this, please reach out to the ops team.

 Refer to the offical [docusaurus documentation](https://docusaurus.io/) on exploring features and adding them to the docusaurus configuration here. To test your changes, the development docker image needs to be rebuilt. Use the following commands to initiate a fresh build of the docker image and create a container using that image.
