 ## Criteria for acceptance of a theme

+### 1. Forks must be notably different
 
 A theme based on an existing Hugo theme (aka a fork) must be notably different for it to be considered a separate theme altogether. In such cases, you should list few arguments in `README.md` file mentioning why your theme should be included. 
 
 The definition of _notably different_ can be subjective, but in most cases, it should be clear. Simply changing the background color or changing few styles, for instance, does not make a theme notably different. It would be better if you submit a pull request to the original theme to include your proposed changes.
