Yes, it's always more powerful (and useful) to tell people what TO do, instead of what NOT to do.

I contribute very occasionally, and by trial and error, I *think* I have found the procedure. (And if it's not right, or not optimal, I would be delighted to learn how to do it better...)

- In Github, fork the official repo into my personal Github account
- Clone my personal copy of the repo to my laptop
- Create a branch for my changes on my laptop

- Monkey around, improve the world, then...

- Squash my commits so that there's only one change (optional, but it tends to improve the commit messages)
- Push my commits back to my personal repo
- From my personal Github account, create a PR for my branch back to the official OpenWrt repo

Do I have the gist of it? Many thanks.
