Making a pull request

Pull from upstream beta to make sure you have the most recent code and create a new local branch to make your changes.

git pull upstream beta
git checkout -b BRANCH_NAME

Once done,

git commit -am "Add a message here"
git push origin BRANCH_NAME

Go to the GUI and you should see a pale yellow bar notifying you a PR can be made. Click that and give it a title referring to the change you made. Add a description referencing why the change was made (including a link to the Trello card prompting the change). Notify another collaborator to review and merge your code if no changes need to be made.
