 The `arkenfox user.js` is a **template** which aims to provide as much privacy and enhanced security as possible, and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen).
 
-Everyone, experts included, should at least read the [implementation](https://github.com/arkenfox/user.js/wiki/1.3-Implementation) wiki page, as it contains important information regarding a few `user.js` settings.
