  <p><code>git init</code></p>
  
  <p>it shows me the error</p>
  
  <p><code>Reinitialized existing Git repository in C:/User/User/Desktop/xxx.git</code></p>

  <p><code>git add .</code> it is ok</p>
  
  <p>when I use the command</p>
  
  <p><code>git commit -m "First commit"</code> it shows me this error</p>
  
  <p><code>On branch master Your branch is ahead of 'origin/master' by 1 commits 
  Nothing to commit, working tree clean</code></p>
  
  <p>And final, when I try to use those command</p>
  
  <p><code>git remote add origin https://github.com/xxx/xxx.git 
   git push origin master</code></p>
