title: Changes not staged for commit git
body: <p>I'm trying to commit my changes to the <code>git</code> but i have this message saying <code>Changes not staged for commit:</code>. Before, the command that I always used is <code>git add-commit -m "message"</code> but now i don't know what syntax used now in this version of git which is <strong>git version 2.15.0</strong>. I looked for the documentation in the <code>git</code> website but no luck. Can someone help me with this?</p>
