git remote -v

14. Add a remote
Let’s create a nickname of the open source project.
upstream sounds like a good nickname.
git remote -v
git remote add upstream <url>
git remote -v

18. fetch, rebase, push
my workflow for keeping things updated
git fetch upstream
git rebase upstream/master
git push origin master

19. branch, checkout
A feature branch keeps your new contribution neat and tidy.
Doing work on a feature branch helps avoid merge headaches later.
git branch new-feature
git checkout new-feature
git checkout -b new-feature

20. git status
Pro tip: use it often.
git status

21. git add
Adds file(s) to the staging area to keep ready before committing changes.
Real world analogy: Boarding an airplane
git add <file(s)>
git status

22. git commit
Commit file(s) in the staging area to the repo history.
Real world analogy: Airplane takes off with all its passengers
git commit -m'Add commit message.'
git status
git log
Note: The commit exists in the local repo only at this point.

23. git push
Shares the local commit with a remote repo.
git push origin new-feature
Note: You must have "push" privileges to push to a remote repo.

24. Another feature
Update the local repo with upstream changes.
Create a new feature branch. Update the origin repo.
git checkout master
git checkout -b another-feature
git fetch upstream
git rebase upstream/master
git push origin another-feature

25. git add <files>
git commit -m"Add commit message"
git status
git log
git fetch upstream
git rebase upstream/master
git push origin another-feature
• Add changed files to staging area of
local repo.
• Commit changed files to local branch
and repo.
• Update (fetch and rebase) the local repo
with any upstream changes.
• Push feature branch to the origin repo.
Another feature: add, commit, fetch, rebase, push

28. Fact: Some projects are more welcoming and encouraging than others.
Myth: Your talent, potential, and future success are defined by a maintainer’s
response to your pull request.
Fact: Your PR may be rejected.
Fact: You may need to make changes based on constructive review
comments.
Myth: Maintainers are entitled to belittle a pull request or be crummy to you.
Fact: It’s not you. It’s them. And their loss. Find another project that values
your contribution.
