Usage of branches

I have a question regarding the branches in Github.

If we merge a branch in develop, and we later want to make a change (update, modify something) in what we implemented in that branch, is it better to work on that branch (merging develop to it to avoid conflicts), or do we create a new branch?

This is related to another question, which is the following. Once we merge a branch, is it suitable to delete it right at that moment or should we keep it for some time? For example, until we deliver what we are doing (for you to see how we worked, for example, or other reason). @pglez82

No files or tests are mentioned. Review the two questions about reusing or recreating branches and deleting merged branches, then check the repository’s current guidance for consistency. Done means adding a clear, agreed answer to this FAQ entry.
