title: How to use MinGW-64 with Qt Creator
body: <p>I am aware that there are many post about this, but I honestly didn't understood any of it.</p>
  
  <p>So, how do I install a kit for my Qt Creator (open source 5.7)?</p>
  
  <ul>
  <li>I already downloaded and installed MSYS2.... don't know what to do with it.</li>
  <li>I already downloaded and installed Qt64 - NG.... no clue what to do next.</li>
  </ul>
  
  <p>I just want to be able to develop in Qt and chose betwen MinGW 32 and MinGW 64.</p>
  
  <p>Thanks in advance!</p>

  <p>EDIT: I also checked the wiki page. Most of the commands didn't worked. And I was told that it is outdated.</p>
