Liberal proofreading and restructuring of README

* Pruned a lot of repetitive text
* Changed many suggestions and "you can .." into imperatives ("do ..")
* Moved images below configuration values (groups all related text,
  easier mental parsing)
More explicit DO NOT EDIT message

Although to be honest, I don't understand what file the user is supposed
to edit in "inside the templates folder". Where are those color values
actually located? Might need some clarification.
