New Contributor: Need Help Understanding PDF.js Codebase

[techwithsatish]

Hi everyone,

I’m new to open source and would like to contribute to PDF.js. I’ve set up the project locally and gone through the README and contributing guidelines. However, I’m having trouble understanding how the rendering logic works in the codebase.

Could someone please point me to the relevant files or provide a high-level overview of how the PDF rendering process works?

Thank you!
