 #### Ready to Add Your Code?
 
 Follow GitHub's fork-branch-pull request pattern.
+
 1. Fork the relevant cFS component (eg. cfe, osal, psp).
+
 2. Create a new branch in your fork to work on your fix. We recommend naming your branch `fix-ISSUE_NUMBER-<FIX_SUMMARY>`.
+
 3. Submit a pull request to the nasa `main` branch. We recommend creating your pull-request as a "draft" and to commit early and often so the community can give you feedback at the beginning of the process as opposed to asking you to change hours of hard work at the end.
+
 4. Add commits to your branch. For information on commit messages, review [How to Write a Git Commit Message](https://chris.beams.io/posts/git-commit/). Please follow commit message convention:
+
 ```
 Fix #XYZ, SHORT_DESCRIPTION
 
 LONG_DESCRIPTION (optional)

 #### How to Amend Commits
+
 1. To modify your last commit message:
+
 ```sh
 git commit --amend
 ```
+
 2. The previous commit message will load an editor session, where you can make changes to the message, save those changes and exit. When you save and close the editor, the editor writes a new commit containing that updated commit message and makes it your new last commit. Push the new changes:
+
 ```sh
 git push --force
 ```
 
 1. To change the actual content of your last commit, stage those changes:
+
 ```sh
-git add <file>
+git add <files-to-amend>
 ```
 2. Amend the commit:
+
 ```sh
 git commit --amend
 ```
 3. Now the last commit is replaced by your new and improved commit. Push the commit:
