 # Cairo Language Server
 
 Scarb is distributed with the `scarb cairo-language-server` extension which is a compilation of the official
-[Cairo Language Server](https://github.com/starkware-libs/cairo/tree/main/crates/cairo-lang-language-server),
+[Cairo Language Server](https://github.com/software-mansion/cairols),
 that is matching the version of Cairo compiler used in Scarb itself.
 Scarb's version of the language server is just a launcher for the original code, unmodified.
 
 ## Visual Studio Code
 
 The Cairo Visual Studio Code extension will start language server from Scarb automatically.
 You do not need to take any further steps.
