Depending upon your issue, the basic format for a branch name is

{your-name}/issue-{issue-number}

We request you follow these guidelines strictly. If your issue does not have a issue number assigned to it (i.e it's not opened) then you are required to open an issue about it, if it's a minor detail then you may not need to open an issue for it and you can follow this convention instead.

{your-name}/issue-{topic}

Here, {topic} can be any of the following

1. Docs
2. Code
3. Typo

Another thing to make sure that before PR merging, if the issue is found out to be not a minor detail and you have still created a PR for it then you are required to at least open the issue for it, link it in the PR body and then proceed, this is to be done to make sure the changes can be discussed upon before finalizing them
