-Kloud Workspace aims to provide the best Python development experience.
-However, due to licensing constraints, limitations exist in language server integrations.
+Kloud Workspace ships **Meta's Pyrefly** as the Python language server — Rust‑based,
+type‑aware, and dramatically faster than alternatives. Strict type checking is on by

-Kloud Workspace is *not* an official Microsoft build of VS Code, and therefore, the proprietary

-
-- Blazing‑fast code completion.
-- Go‑to‑definition & symbol search.
-- Basic refactorings.
