# Requirements

> System requirements for the LinkEnhancer module

---

This module requires **webtrees** version 2.2 or 2.3.
This module has the same requirements as [webtrees#system-requirements](https://github.com/fisharebest/webtrees#system-requirements).

It was initially created for version 2.2.4; since linkenhancer 1.6.1 it should also work with webtrees 2.3. Tests were usually run with built-in themes and some other custom modules.

> **Tip:** It's recommended installing the [Cronjob](../../cronjob) module as well. This makes it easy to run the CLI scripts for maintaining the indexes.
