## Technical documenation

This documentation is the interesting part for administrators and developers and should explain how lux can be
installed, configured and how does it work. In addition we want to give you some hints how to extend lux with your own
workflow triggers or workflow actions.

### Introduction

Lux is build to use asynchronical techniques and without the need of any USER_INT function to also use lux together with
staticfilecache extension for **high performance** on your TYPO3 websites.

There is **no need to use a JS framework like jQuery** - Lux just uses vanilla JS - also for the lightbox implementation.

But TYPO3 should run in **composer mode** to allow the loading of additional packages (see Installation for more
details).

Tracking and doing workflow stuff in frontend needs **JavaScript** to be enabled in the visitors browser. Some functions
are disabled if the visitor is also logged in into backend at the same time (to avoid misleading data).
It's possible for visitors to opt out (with the opt-out plugin) or to use the *do not track* settings in their browser.
Lux will respect this settings in every case.

Every visitor gets an individual identificator, which is used to recognize the visitor in future visits.
Per default this is a random string, saved to the localstorage of the browser. Alternatively LUX can work cookieless
with an anonymous hash (fingerprint), based on the visitors hard- and software - see
[Fingerprints vs. local storage](../Privacy/FingerprintsAndLocalStorage.md).

There are some settings - saved to localstorage in browser which are:
* `luxId` the identificator of the visitor (only in localstorage mode - the default)
* `luxDisableEmail4Link` to disable email4link popups if a visitor is already identified
* `luxTracking` for a tracking opt out or opt in
