+# Microsoft Teams
+
+There is no Microsoft Teams client package that you can install on Linux. The official client provided by Microsoft is a PWA ([Progressive Web App](https://en.wikipedia.org/wiki/Progressive_web_app))
+
+For this to work you need an up-to-date browser on your linux system. 
+
+To "install" the app simply point your browser to: https://teams.microsoft.com
+
+Afterwards you should have the full teams functionality available.
+
+More details to come ...
