## Optional Step 4. You may choose to add additional lines of code. You may also choose to add additional comments. ## Step 5. Create a new commit in Git and push it to GitHub. ## Step 6. Create a new branch in GitHub called 'lab6.3-change-file-name'. ## Step 7. In the new branch, change the file name and push it to GitHub.
