+Citrix Workspace known issues
+-----------------------------
+
+These are known issues when running the desktop client in a Citrix workspace:
+  - The Windows user's Roaming profile needs to be persisted between sessions.
+    The failure on doing so will result in result in users having to set up their account again in every new session.
+  - The user's synchronization folder also needs to be persisted between sessions. 
+    The client will throw errors because it can not find the sync folder once the users logs in a new session.
+  - Every time the user logs in a Citrix environment, it creates a session with the desktop client and in that session the client will sync the user's files, 
+    that can quickly lead to the storage running out of space.
