Ideally you have someone experienced in the codebase who can give a lay of the land.

I suggest:

1. Find a senior dev, ask then for exisiting pointers to good documentation to self learn.

2. give that a go, make note of all the questions you have

3. then have a session with that dev for platform walk through. Take lots of notes and ask your questions.

4. offer to update docs where you found errata or missing steps or even complete topics not mentioned

5. suggest to the team anything about onboarding that can be improved.

This is exactly what I would do ideally except I couldn't. I can understand that working in startups you would overlook alot of theory and due to hectic nature low quality calls(code/architecture explanation) are not appreciated.

And that's why the first thing I ask during a technical interview is "Do you have internal documentation?".
