About a year or so ago, GitHub announced that GitHub Actions was generally available. GitHub Actions allows anyone to “automate their workflow” - in other words, run code on committed code - on GitHub’s own servers, and share those actions.
After making a few changes to this blog in an attempt to appease Amazon and failing, I wanted to undo those changes. Thankfully, since this blog is hosted on GitHub pages, it’s versioned controlled via Git. Meaning I should easily be able to find the changes and undo them fairly easily.
So you want a custom 404 page for your project page, or just any subdirectory? Well, according the GitHub help page, “you must use a custom domain.”
