-This request build upon the current `textDocument/hover` to show the type of the expression currently selected.
+This extension allows passing a `Range` as a `position` field of `HoverParams`.
+The primary use-case is to use the hover request to show the type of the expression currently selected.
 
 ```typescript
-interface HoverParams extends lc.WorkDoneProgressParams {
-    textDocument: lc.TextDocumentIdentifier;
-    position: lc.Range | lc.Position;
+interface HoverParams extends WorkDoneProgressParams {
+    textDocument: TextDocumentIdentifier;
+    position: Range | Position;
 }
 ```
-
 Whenever the client sends a `Range`, it is understood as the current selection and any hover included in the range will show the type of the expression if possible.
