+.. admonition:: Who develops Nextcloud?
+
+  The development of the Nextcloud platform is a cooperative
+  endeavor overseen by the core maintainers -- primarily
+  employed by Nextcloud GmbH -- along with thousands of
+  partners, providers, collaborators, project members, and 
+  community participants.
+
+  The Nextcloud community includes everyone -- from individual 
+  users and independent developers to large organizations.
+
+  Community members share and discuss their experiences with 
+  the platform every day. They suggest improvements, 
+  collaborate on design, write code, create documentation, 
+  test for bugs, triage bug reports and enhancement ideas, 
+  support others, improve translations, and help fund and 
+  organize the logistics of a project this size. Most 
+  importantly, they use Nextcloud in their daily lives and 
+  work.
