The explanations used in the article were prepared using Genie, a "Codebase explainer" that we built using langchain. Our hopes is that developers would be able to use it to accelerate their understanding of new codebases and empower themselves with tools to become an 10x open-source contributor!
BTW, if you're curious to learn more about Genie and how it can supercharge your code repositories with QnA capabilities, do visit our website at www.birdlabs.ai for more details :)
