1. create local branch
   • terminal git branch branchname from the branch you want to start off (git branch will duplicate the current branch and give it a new branchname). If the branch is already created in the remote, checkout to its tracking-branch, and branch from there
   • magit b l checkout local branch or b c create branch would let you decide which branch/tracking-branch to start off.
2. push local branch to origin(remote repo) and create it at the remote repo

pull request is basically telling a project maintainer to pull your code to try it out on their local machine, and decide if to merge.

In order to do that, you need to provide with project maintainer the following informations:

• your repo’s url and the start/end commit of your patch, for the project maintainer to perform git pull

Esssentially, it is not part of git’s utility, and in its whole done by people by hand: you send message to the project maintaner about your patch, project maintainer try it out and tell you to change something, reject it, or merge it.

git book have this example

$ git request-pull origin/master myfork

the command generates this message for you to include in your email to the project maintainer. The git repository is not meant to be local repository, but a public one that the project maintainer would have access to(you can tell from the domain name)

In various git service providers, they made services to make pull-request in the same platform which is roughly like this, just they have buttons to automate some of the commands listed here:

    git checkout -b userblah-test master (added master here and in the next line)
    git pull https://github.com/userblah/myproject.git master
    look at changes
    git checkout master
    git merge userblah-test
    git push

• mainly pulling and merging
