Steps to push your local files to the 'remote' GitHub repository.
1.  Copy the file to the location that you wanted to push (example: DNN-CFFs/work/folder-name)
2. In the terminal, navigate to the same location using 'cd' (change directory) command
   example: cd DNN-CFFs/work/folder-name
3. Type ' git status' and press enter. It will show the new file name  (or the modified file name) in 'red' color.
4. Type 'git add <file_name>' and press enter.
    example: git add README.md
5. Type 'git commit -m "add a comment about the change that you did to the code/file that you are going to push within this double quotes"
6. Type 'git push'   

Make sure that you have accept the traction-tools invitation from your email.

If this didn't work, then type 'git remote set-url origin git@github.com:uva-spin/DNN-CFFs.git'
   If it still complaining that you have to login/add-ssh-key then follow the instructions on the following link for "Adding a ssh key" and then use the above line to establish the git remote set-url origin. After that, try 'git push' and it should work.
