 ## Overview
 
-Glint is a set of tools to aid in developing code that uses the Glimmer VM for rendering, such as [Ember.js] and [GlimmerX] projects. It's particularly focused on static analysis of templates via TypeScript and the richer editing experience that that enables for both TS and vanilla JS projects.
+Glint is a set of tools to aid in developing code that uses the Glimmer VM for rendering, such as [Ember.js] and [GlimmerX] projects. Similar to [Vetur] for Vue projects, Glint consists of a CLI and a language server to provide feedback and enforce correctness both locally during editing and project-wide in CI.
 
-⚠️ Note: **Glint is still under active development!** Please bear with us and expect breaking changes and rough edges as we work toward a stable release. Also note that Glint is currently only compatible with TypeScript projects.
+⚠️ Note: **Glint is still under active development!** Please bear with us and expect breaking changes and rough edges as we work toward a stable release. Also note that Glint is currently only compatible with TypeScript projects, but our aim is ultimately to support JavaScript as well, as TypeScript's tooling can provide best-in-class support for both TS and JS projects.
