Need a document to understand the code

Hello, thanks for sharing this project.

Do you have a document that describes the structure of the code in this project? I can not find any on the internet or on this page https://www.chromium.org

Thank you!

Start by surveying the AndroidChromium repository and any existing documentation to identify the main code areas and their relationships. Done means publishing a document that explains the project's code structure clearly enough for a newcomer to navigate it.
