If you make a mistake in a commit message but HAVEN'T pushed it yet, you can change that commit message with --amend:

git commit --amend -m "New message"

This won't change any of the files in your commit - but will rewrite the commit with the new message.

To start a new Git project, go to New on Github and enter a repository name. After creating the repository, find the clone link for the repo and git clone <repo-link>. You can then cd into that folder and touch index.html to create your first file. Inside your index.html file you can insert code and add the file to your commit.

index.html

<html>
  <head>
  </head>
  <body>

    <h1>Fixing git mistakes</h1>

  </body>
</html>  

You can do a git status and see that the index.html is an untracked file. Once you , it stages the file and prepares it for a commit. You can commit that with a message like .
