@amyli21 Thanks for reading the tutorial and submitting a Pull Request!

Your PR includes the files readers/ali527.txt and readers/amyli.txt. The goal is that every contributor names the files using their own username, which in your case would be amyli21.txt.

This is a great opportunity to practice updating a Pull Request after receiving feedback. This will often happen when you contribute to other projects. Running the code below from the git-for-science repository on your local machine will update the filename, commit the change, and then push the change back to GitHub.

# Rename one file, delete the other
git mv readers/amyli.txt readers/amyli21.txt
git rm readers/ali527.txt
# Commit the change
git commit -m "Change filename to username"
# Push the changes back to your fork. The PR will automatically update
git push origin master

Please do not hesitate to ask if you have any questions!
