+## About
+Uses the client build in API with the -t argument.
+For more information, see [[VirtualHere Client API documentation](https://www.virtualhere.com/client_api)].
+Client configuration file is stored in home assistant config directory and named vhclient.ini, for easy access.
+
 ## How to use

+
+## Configuration
+

+
+### Option: 'AUTOFIND'

+
+### Option: 'USB devices'

+
+### Option: 'No client config'

+
+### Option: 'ClientId'
+This adds a custom 'In use by ...' on the server. Edits the vhclient.ini (Section General, value ClientId).
+
+### Advanced Option: 'MANUAL HUB'
+Specify server hub to connect to. Corresponds to client API "MANUAL HUB ADD", but edits the vhclient.ini directly (Section Settings, value ManualHubs). Both IP and port is needed.
