I disagree, since it’s opensource the codebase it constantly evolving and it would be really really hard to maintain a documentation for the codebase, secondly, I’m with you, it might seem a bit daunting at first but you just need to get your hand dirty and dwell in the code base, piece by piece it will start making sense, one recommendation I can give you for easy navigation is use the search file feature in VSCODE, by typing few keyword you can easily find out which file is affecting the part of the codebase you want to edit.
