   Ideally, Emacs should have a major mode for each programming
 language that you might want to edit.  If it doesn't have a mode for
 your favorite language, the mode might be implemented in a package not
 distributed with Emacs (@pxref{Packages}); or you can contribute one.

+** Emacs can be built with the 'tree-sitter' parsing library.
+This library, together with grammar libraries, provides incremental
+parsing capabilities for several popular programming languages and
+other formatted files.  Emacs built with this library offers major
+modes, described elsewhere in this file, that are based on the
