 A `user.js` is a configuration file that can control hundreds of Firefox settings. For a more technical breakdown and explanation, you can read more on the [overview](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.1-Overview) wiki page.

-The [ghacks user.js](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/user.js) is a template, which, as provided, aims (![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/exclamation.png) with [extensions](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-B:-Extensions) <sup>1</sup> ) 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).
+The `ghacks user.js` is a **template**, which, as provided, 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).
 
-We aim to INFORM and give you CHOICES. No one size fits all, so customize it! And not all sites have the same requirements, so use [profiles](https://github.com/ghacksuserjs/ghacks-user.js/wiki/2.3-Concurrent-Profiles) with custom versions. We won't set you wrong.
+Everyone, experts included, should at least read the [implementation](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation) wiki page, as it contains important information regarding a few `ghacks user.js` settings.
 
-INFORMATION IS POWER. So you can make informed decisions to better protect yourself online, we aim to be:
-
-* Accessible (provide information and simpler, less-technical descriptions if possible)
-* Accountable (provide reputable references/sources, [test sites](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-C:-Test-Sites), dispel bad advice)
-* Change trackable (yay! we're on github now, with commits)
-* Compatible (including a [deprecated section](https://github.com/ghacksuserjs/ghacks-user.js/issues/123), [releases](https://github.com/ghacksuserjs/ghacks-user.js/releases))
-* Comprehensive (including enforcing defaults and future-proofing)
-* Current and up-to-date with stable (including [changelogs](https://github.com/ghacksuserjs/ghacks-user.js/search?q=label%3Achangelog&type=Issues&utf8=%E2%9C%93))
-* Detailed (preference versioning, hidden preference information, explanations, and more)
-* Easy to use and discuss (sections, sub-sections, numbering)
-* Helpful (including a [wiki](https://github.com/ghacksuserjs/ghacks-user.js/wiki) with features such as [extensions](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-B:-Extensions), [user scripts](https://github.com/ghacksuserjs/ghacks-user.js/wiki/3.1-User-Scripts), [references](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-D:-References) and more)
-* Innovative (formatting, special tags, and future plans such as branches)
-
-### ![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/bullet01.png) usage
-Everyone, experts included, should at least read the [implementation](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation) wiki page, as it contains important information regarding a few default settings we use. The rest of the [wiki](https://github.com/ghacksuserjs/ghacks-user.js/wiki) is helpful as well.
