This folder is the Zixir Language Client extension (syntax, LSP client).

Use this folder, not the repo root.

1. In VS Code: Ctrl+Shift+P → Developer: Install Extension from Location...
2. Choose the .vscode folder:
   • c:\Users\Legion\Desktop\ExlirZig\.vscode
   • Or the full path to the repo’s .vscode directory on your machine.

VS Code expects a folder that contains a package.json with engines.vscode. That file is here in .vscode/; the repo root has mix.exs and is not an extension, so selecting the repo root will fail.

From the repo root:

cd .vscode
npm install
npm run compile

Then install from location (path = .vscode as above).
