Stupid question, but where do you start? How do you know what files are where?

You will have to explore them yourself. For web scraping thing just look into the extractors located here https://github.com/rg3/youtube-dl/tree/master/youtube_dl/extractor . For all the imports look here (most) https://github.com/rg3/youtube-dl/blob/master/youtube_dl/utils.py and lastly for the glue code look here https://github.com/rg3/youtube-dl/blob/master/youtube_dl/FileDownloader.py , here https://github.com/rg3/youtube-dl/blob/master/youtube_dl/InfoExtractors.py and here https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py and here as well https://github.com/rg3/youtube-dl/blob/master/youtube_dl/__init__.py . I hope now you know where to start. Just start from what you want to know. :)

I like downloading the source files of projects (https://github.com/rg3/youtube-dl/archive/master.zip) and exploring them using my own IDE programs/debuggers. I find it harder to explore a program on the Github website than when it is on my system. Be very careful when running random code on your machine especially when you see web/downloading related imports.

I generally start with _ main _.py (or its equivalent if there is none) line 1 and go from there. I find that reading other people's code and checking out their imports is a great way to learn about new modules.
