Open a terminal window and set the project's directory to the working directory using the cd command. In this case "/home/opnfv/yardstick" is the path to the Yardstick project folder on my computer. Replace this with the path of your own project.
Tell Git which files you would like to take into account for the next commit. This is called 'staging' the files, by placing them into the staging area, using the 'git add' command (or the synonym 'git stage' command).
