Conflict Practice Repo

Now with a first-month-free promo. See pricing.md.

Clone this, then try:

1. git fetch origin
2. git checkout feature/pricing
3. git rebase main (or git merge main)
4. Resolve the conflicts in pricing.md and README.md
5. Continue the rebase / commit the merge
6. git push --force-with-lease (only after rebase, on your own branch)
