+# Development Container
+
+This folder contains the [Dev Container](https://containers.dev/) configuration for
+contributing to **AI Engineering Coach**. It provides a one-click, reproducible
+development environment for the VS Code extension.
+
+## What you get
+
+- Node.js 22 (LTS) on Debian Bookworm
+- `npm install` runs automatically after the container is created
+- GitHub CLI (`gh`) preinstalled
+- Recommended VS Code extensions preinstalled:
+  - ESLint (`dbaeumer.vscode-eslint`)
+  - TypeScript Next (`ms-vscode.vscode-typescript-next`)
+  - Vitest Explorer (`vitest.explorer`)
+  - Code Spell Checker (`streetsidesoftware.code-spell-checker`)
+  - Playwright Test (`ms-playwright.playwright`)
+
+## How to use it
+
+### GitHub Codespaces
+Open this repository on GitHub and choose **Code → Codespaces → Create codespace
+on main**. The container will build and dependencies will install automatically.
+
+### VS Code (Dev Containers extension)
+1. Install the [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+   extension.
+2. Open the cloned repository in VS Code.
+3. Run **Dev Containers: Reopen in Container** from the Command Palette.
+
+Once the container is ready, run `npm run check` to verify your setup (typecheck,
+lint, spellcheck, knip, and tests).
