+### VS Code (Unreleased)
+
+A VS Code extension lives in `editors/vscode`. The extension manages
+the `codebook-lsp` binary for you, starts it with the right flags, and exposes a
+few configuration toggles (`codebook.binaryPath`, `codebook.enablePrerelease`,
+and `codebook.logLevel`).
+
+To try it locally:
+
+```sh
+cd editors/vscode
+bun install       # or npm install
+bun run build
+bun run package   # or npm run package
+code --install-extension codebook-vscode-*.vsix
+```
+
+Once the extension is installed it will activate automatically for every
+supported language.
+
+**Note**: This extension is a work in progress and is not in the Marketplace yet. If you try it out, we'd love feedback!
+
 ### Other Editors
 
 Any editor that implements the Language Server Protocol should be compatible with Codebook. To get started, follow the [installation instructions](#installation), then consult your editor's documentation to learn how to configure and enable a new language server. For your reference, the following command starts the server such that it listens on `STDIN` and emits on `STDOUT`:

+# Codebook VS Code Extension (Unreleased)
+
+**Note** This extension is a work in progress and is not released on the VS Code marketplace yet. However, it is functional. Follow the Development instructions to install if you'd like to provide feedback!
+
+This extension wires the Codebook language server into VS Code so code-specific
+spell check diagnostics and quick fixes appear automatically.
+
+## Features
+
+- Automatically launches `codebook-lsp` for supported languages.
+- Downloads, caches, and updates the Codebook language server without requiring any manual installation.
+- Supports custom binary locations and optional pre-release builds via
+  `codebook.*` settings.
+
+## Development
+
+```
+cd editors/vscode
+bun install   # or npm install / pnpm install
+bun run build # or npm run build
+bun run package # builds dist/ and emits a .vsix via vsce
+```
+
+The emitted JavaScript lives in `dist/` and can be loaded into VS Code via the
+`Extension Tests / Run Extension` launch configuration or by using the bundled
+`vsce` CLI via `bun run package`.
+
+Set `codebook.logLevel` to `debug` to see verbose logs from the language server
+inside the `Codebook` output channel.
