I contributed to a few open source projects over the years, but I only focused on solving the problem I had, either a bug I wanted to fix or a feature I wanted to add. Once my issue was resolved, I didn't really care much about the rest of the project. I found it was less of a learning opportunity.

That's why I created this project to really track down the codebases that you can read from start to finish and learn how they are designed and implemented. Currently it only lists a few codebases that I actually have read. They are mostly small-size projects. I'd like to hear advice on how to approach and learn from a large project.
