# Getting started

This documentation supports the admin to carry out the necessary steps to do installation of the HXA.io applications and systems easily and quickly.

The HXA.io applications and systems need a connection to the internet to communicate with the HXA.io services which are providing the data from Microsoft 365 (Exchange Online) or Microsoft Exchange On-Premise. The whole configuration is done in the HXA.io Portal at https://portal.hxa.io.
