System requirements
===================

Group-Office 6.6 has the following requirements in order to be officially supported:

.. table:: Software
   :widths: auto

   ====================  ===========
   Type                  Requirement
   ====================  ===========
   Operating System      Linux / Docker

   ====================  ===========

.. note:: Group-Office will run on Nginx, but we currently have no documentation on this.

PHP 8 support
-------------

Group-Office 6.6 is **not** officially supported with PHP8. We do backport PHP8 compatible code in the 6.6 branch when
possible. The community version may run fine, but the paid modules probably won't.
