title: How to restore github repository
body: <p>I deleted local git repository and remake local git repository. after that 
  I pushed one project into remote repository by using below command </p>
  
  <pre><code>git push -f origin master
  </code></pre>
  
  <p>but when i checked my projects on Gihub, I found out that there is nothing except one project which i just pushed from local repository.
  all existing project disappear. it's like master branch is overwritten. 
  I know i should fetch first before doing 'push'. I did't even clone<br>
  is there any solution to restore? 
  I want to turn it back to prior Gihub master version.</p>
