+VS Code or run:
+
+```text
+ext install wrnexus.wrnexus
+```
+
+For a local package, open the Command Palette, choose **Extensions: Install from
+VSIX**, and select the generated `wrnexus-<version>.vsix` file.

-## Building the diagnostics engine
+To format automatically when saving, add this to VS Code settings:
 
-Diagnostics use a bundled copy of the compiler. Regenerate it after changing
-`@wrnexus/compiler`:
-
-```bash
-bun run build:compiler   # writes src/compiler.cjs
+```json
+"[wrn]": {
+  "editor.defaultFormatter": "wrnexus.wrnexus",
+  "editor.formatOnSave": true
+}
 ```
 
-The extension still highlights, snippets and completes without the bundle; only
-inline error reporting requires it.
+## Privacy
+
+The extension does not collect telemetry and does not send source code or usage
+data over the network. Formatting, completion, and diagnostics run locally.
 
 ## Development
 
+Diagnostics use a bundled copy of the compiler. Build and validate everything
+after changing the extension or `@wrnexus/compiler`:
+
+```bash
+bun install
+bun run check
+bun run package
+```
+
+`bun run package` creates `wrnexus-<version>.vsix`. The extension still
+highlights, provides snippets, and completes without the compiler bundle; only
+inline error reporting requires it.
