This Week in Open Source

Sara Jackson

I’ve expanded on the definition of “this week” to actually mean “3 weeks that occured in March.” 👀 At least for today.

The theme of this edition is dynamic README workflows. Have you heard the word? You can read more about the work Stefanni Brasil (stefannibrasil) and Akshith Yellapragada (ayellapragada) did in this this blog post.

A summary of thoughtbot open source projects that have had the workflow added can be seen at the end of this post.
