+## Accessibility Service (optional)
+
+kboard provides an accessibilty service which can be used to populate a person's name from Whatsapp conversations.
+
+This can be accessed with the keywords `$name`, `$fname` and `$lname`.
+
+This service is optional, and the keyboard is fully functional without it.
