Use branches and small pull requests to review your own changes and make rollbacks easier.
The core idea
A branch lets you isolate a change from the main line. A pull request provides a review point for diffs, tests, and discussion even when you are the only developer. Small changes are easier to understand and revert.
A practical way to approach it
Create a branch for one task, commit focused changes with descriptive messages, open a pull request, run checks, and merge after reviewing the diff. Delete the branch after merging if it is no longer needed.
Try it in a small project
For a homepage redesign, separate content changes from a backend migration. Preview each change and test the pages it touches before merging.
Common mistakes to avoid
Do not commit secrets or generated build clutter. Avoid rewriting shared history on a branch other people are using.
Key takeaway
Keep the first version small, make your assumptions explicit, and verify the result with a repeatable test. For production use, check the current official documentation for the tools and versions you choose.
