+## What is OnlyOffice
+
+From https://en.wikipedia.org/wiki/OnlyOffice
+
+:::note
+OnlyOffice, stylized as ONLYOFFICE, is a free software office suite developed by Ascensio System SIA, a company headquartered in Riga, Latvia. It features online document editors, platform for document management, corporate communication, mail and project management tools
+:::

+This is based on authentik 2021.10.4 and OnlyOffice 11.5.4.1582. Instructions may differ between versions.
+:::
+
+## Preparation

+
+Create an application in authentik, and create a SAML Provider by using *SAML Provider from Metadata*. Give the provider a name, and upload the XML file you've downloaded in the previous step.

+Edit the resulting Provider, and ensure *Signing Certificate* is set to any certificate.
+
+Navigate on the *Metadata* tab on the Provider page, and click *Copy download URL*.
