 ## Appendix: Miscellaneous Advice
 
 ### Updating a commit after running git push:
 
-Suppose you would like to update a commit that has already been pushed to the
-remote repository. If the commit you wish to update is the most recent
-commit you have made, after making your desired changes, stage the files
-(either using git add or in git cola), and amend the commit. To do so,
-if you are using the command line, run `git commit --amend`. If you are
-using git cola, click on the gear icon located on the upper left side under
-**Commit** and select **Amend Last Commit** in the drop down menu. Then, stage
-the files you have changed, commit the changes, and run git push to push the
-changes to the remote repository. Your change should be reflected in Gerrit as
-a new patch set.
-
-If, however, the commit you wish to update is not the most recent commit you
-have made, you will first need to checkout that commit. To do so, find the
-URL of the commit on <https://review.coreboot.org> and go to that page; if
-the commit is one that you previously pushed, it can be found by selecting
-**My** and then **Changes** in the upper left corner. To checkout this commit,
-in the upper right corner, click on **Download**, and copy the command listed
-next to checkout by clicking **Copy to clipboard**. Then, run the copied
-command in your coreboot repository. Now, the last commit should be the most
-recent commit to that patch; to update it, make your desired changes, stage
