Some basic git commands I used today to set this up:
git init initialises a local repository
git add stages the work to Index
git commit -m "comment" saves the work to the repository
Now the locally saved work can be added to the remote repository.
First you want to connect to the remote server:
git remote add origin git@github.com:SophMC/notechain
git push -u origin master -u is added the first time, after that you just
need to be inside the local repo that you want to push and type
git push
