##Checking out Pull Requests locally
Let's say someone's made a pull request from their fork into your repository. Here's how you can check out her changes on your machine and verify that everything is a-okay.
###Modifying your git configuration
Locate the section for your GitHub remote in your .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:<USERNAME>/<REPO_NAME>.git
Now, add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section.
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:<USERNAME>/<REPO_NAME>.git
fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
Now, fetch all the pull requests:
$ git fetch origin
# From github.com:joyent/node
# * [new ref] refs/pull/1000/head -> origin/pr/1000
# * [new ref] refs/pull/1002/head -> origin/pr/1002
# * [new ref] refs/pull/1004/head -> origin/pr/1004
# * [new ref] refs/pull/1009/head -> origin/pr/1009###Checking out a particular pull request
You can check out a pull request in your repository with the special pr/<:id> syntax, where <:id> is the number of the pull request you're interested in. For example, to check out pull request #999:
$ git checkout pr/999
# Branch pr/999 set up to track remote branch pr/999 from origin.
# Switched to a new branch 'pr/999'
