Cant make jquery to work

Cant make jquery to work

I cant make anything work, this is my code in sublime text 2

  1. <!--script type="text/javascript" src="JQM/jquery.mobile.custom.js"></script>

  3. <link rel="stylesheet" href="JQM/jquery.mobile.custom.structure.css"/>

  5. <link rel="stylesheet" href="JQM/jquery.mobile.custom.theme.css"/-->

  7. <link rel="stylesheet" href="JQM/memotest.css"/>
  8. <script type="text/javascript" src="JQM/memotest.js"></script>


  11. <link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jquerymobile/1.4.2/jquery.mobile.min.css" />
  12. <script src="//ajax.googleapis.com/ajax/libs/jquerymobile/1.4.2/jquery.mobile.min.js"></script>

plz help. I dont know what files I must use. Does jquery and jquery mobile have the same API or they share some methods? Is better to use both or just 1?

note: memotest are just my files to test lol.
