 ## Advice on pull requests:
 
 Pull requests are the easiest way to contribute changes to git repos at Github. They are the preferred contribution method, as they offer a nice way for commenting and amending the proposed changes.
 
 * You need a local "fork" of the Github repo.
-* Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request. Workflow using "feature_x" as the example:
+* Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request. Workflow using `feature_x` as the example:
   - Update your local git fork to the tip (of the master, usually)
   - Create the feature branch with `git checkout -b feature_x`
   - Edit changes and commit them locally
-  - Push them to your Github fork by `git push -u origin feature_x`. That creates the "feature_x" branch at your Github fork and sets it as the remote of this branch

   - When you now visit Github, you should see a proposal to create a pull request
 
 * If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then use `git push` to automatically update the pull request.
