Edits to index

This was my first change using these commands:

#Create a new branch
- git branch [new branch name] : creates a new directory
- git checkout [branch name] : toggles to a branch
- git status

# Commit new files to Git
- git add [filename] : 
- git commit -m "comment" :
- git push -u origin [branch name]: (include branch name if you want to only push branch name and "-u" is only needed to track upstream changes)
