Apply Upstream Pull Request to Local

There are 2 ways:

Using GitHub CLI gh

If local branch has the same base branch as upstream:

Copygh PR checkout {PR#}

Using Patch Files

If local branch diverges from the branch in which the PR is based, then we need to create patch files.

Copygit fetch --all
git format-patch -1 <sha>

the -1 flag tells Git how many commits should be included in the patch;

-
Prepare patches from the topmost commits.

Then checkout the main/master branch and use TortoiseGit to apply the patch. Resolve any conflicts that arise.
