Github has always been able to serve static contents through Jekyll using Github pages. Github pages has enabled millions of static pages to be published easily and for free. The only downside of it has been that Github supports limited number of Ruby gems.

With the introduction of Github action, we can now run linux on Github and build jekyll sites or any other to create a blog.

Using Trello as content management tool, we can integrate Trello with Jekyll to generate blog for free. Trello cards are easy to create as well as edit them as required.

Example: Github workflow for creating blog with Github action.
