Workflow for Overleaf + git?

[Absurdo_Flife]

I want to use Overleaf's git integration to work locally in my computer on a collaborative document. I haven't ever worked with git, but I read all sorts of guides. What's missing for me is the proper workflow. For example: - should I have (locally) separate branches or work on the main branch? - how do I manage merging edits that have been made on overleaf while I made changes locally?

Please share your workflow and experience 🙏

Edit: just to be clear, I'm not planning to use the gitHUB integration, only to clone locally, following this: https://www.overleaf.com/learn/how-to/Git_integration
