How to squash Git commits

A really quick step-by-step guide on how to squash Git commits to make your PRs concise, easy to read, and hence easy to review.

Steps:

• Make sure your branch is up to date with the main branch.
• Run git rebase -i main.
• You should see a list of commits, each commit starting with the word "pick".
• Make sure the first commit says "pick" and change the rest from "pick" to "squash". -- This will squash each commit into the previous commit, which will continue until every commit is squashed into the first commit.
• Save and close the editor (press Esc key, type :w and hit Enter key) -- save a file and quit vim / Vi by pressing Esc key, type :x and hit Enter key.
• It will give you the opportunity to change the commit message.
• Save and close the editor again.
• Force push the squashed commit: git push --force-with-lease origin.
