-## Tree-sitter ##
-The package `verilog-ts-mode` provides syntax highlighting,
-indentation and a backend for hierarchy extraction, definitions and
-references navigation, and some other features implemented in
-`verilog-ext`. Using tree-sitter as a backend is recommended as it is
-much faster and efficient than internal Emacs lisp parsing.
+## Tree-sitter support ##
+
+Some of the features that `verilog-ext` provides are based either on
+builtin `verilog-mode` Emacs lisp parsing or on tree-sitter `verilog-ts-mode`.
+
+It is possible to set up different backends for hierarchy extraction and
+workspace tags collection for completion and navigation of definitions
+and references.
 
-`verilog-ts-mode` is derived from `verilog-mode` making AUTOs and other utilities still available.

-To run the whole ERT test suite change directory to the `verilog-ext` root and run the `test` target:
+Then run the default target:
