Questions beginner developer

Hi fellows,

I want to put html templates. Tell me answers to such questions:

  1. What should be the structure of the template files? .css in css, .js in js
  2. What should be the comments and notes in the files (js/css/html)?
  3. Do I need to upload a license file? If so where and what?
  4. Is there an example for the design template files?
  5. Do I have to do the documentation for the template? If I need to do it on any example?
  6. How long is the template test now?
