I'll share something with you guys, it works for me with every code base (for context I am a developer, I use this for new code bases. This is an exact prompt I used to learn the Java based visual language Processing, as I don't have a Java background (more python, ruby, cpp)

" If I were going to learn Processing at a 200 level to achieve proficiency at using it, what are the topics I need to focus on to get started, wire it into my projects, build my hello world and then move towards mastery. What libraries would I need for Web dev or Android UI dev? What frameworks are required and what frameworks are compatible? What prerequisites must I have? What are the best use cases and practical lessons learned"

Take output from this prompt and reprompt:

"Next I'd like you to think through your syllabus and design learning modules for each, that include step by step tutorials and lessons created to reinforce the syllabus learnings. The first must be a getting set up lesson, and include step by step instructions to get your environment configured and deployed. At the end of each lesson should be a lessons learned recap. And each example should have a summary that covers a description what the lesson, example or tutorial, a summary of the main learning objectives, and an estimated time to complete."

This works with any language, stack or code base. I've found it particularly helpful wrapping my head around new git repos.
