19. Push
● No push to master : NEVER
Neither no force push : rewrite history
Solution : git revert or git rm --cached

20. Pull
● pull rebase >>>>>> pull merge
Bad for the history : Messy graph
git pull --rebase=preserve

21. Conflicting Pull Request
● Grab the PR locally, merge and manually push
- git fetch origin refs/pull/23/head
- git checkout master
- git merge FETCH_HEAD
- Manually solve, add and commit
- git push origin branch

22. Issues
● Use predefined labels and alias code

23. Licenses
● No licenses is not “do what you want”
● Choose a license
● Read README.md and CONTRIBUTING.md
https://choosealicense.com/

24. GitHub Actions
● Make workflow automations easy
● Free plan
