+    These classes are used to provide code assist support such as completions and refactoring
+    actions for editors.
+
+    Completions can be of a variety of kind like function hints, snippets, and regular
+    context-aware content. The later are usually represented by semantic proposals, but
+    it is also possible that they are simply plain text as supported in the fake vim mode.
