+## VS Code Integration
+
+VS Code can connect directly to a running opencode-devbox container for a full IDE experience with IntelliSense, debugging, and extensions running inside the container.
+
+**Requirements:** Install the [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension. For remote Docker hosts, also install [Remote - SSH](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh).
+
+**Steps:**
+
+1. Start the container: `docker compose up -d`
+2. In VS Code: `Ctrl+Shift+P` → "Dev Containers: Attach to Running Container" → select `opencode-devbox`
+
+For remote Docker hosts (e.g. connecting to a server via SSH), first connect to the remote host with Remote-SSH, then attach to the container from there.
+
+VS Code extensions installed inside the container persist as long as the container exists. For persistent extension storage across container recreations, add a named volume:
+
+```bash
+docker run -it --rm \
+  -v devbox-vscode:/home/developer/.vscode-server \
+  ... \
+  joakimp/opencode-devbox:latest
+```

 ## Using docker-compose
 
 Create a directory with a `docker-compose.yml` and a `.env` file:

+### VS Code integration
+
+VS Code can connect directly to a running opencode-devbox container for a full IDE experience with IntelliSense, debugging, and extensions running inside the container.
+
+**Local Docker (Docker running on your workstation):**
+
+1. Install the [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension
+2. Start the container: `docker compose up -d`
+3. In VS Code: `Ctrl+Shift+P` → "Dev Containers: Attach to Running Container" → select `opencode-devbox`
+
+**Remote Docker (Docker running on a remote server, e.g. via SSH):**
+
+1. Install the [Remote - SSH](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh) and [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extensions
+2. Connect to the remote host: `Ctrl+Shift+P` → "Remote-SSH: Connect to Host"
+3. On the remote host, start the container: `docker compose up -d`
+4. In VS Code (now connected to the remote): `Ctrl+Shift+P` → "Dev Containers: Attach to Running Container"
+
+VS Code extensions installed inside the container persist as long as the container exists (not removed with `docker compose down`). For persistent extension storage across container recreations, add a named volume:
+
+```yaml
+volumes:
+  - devbox-vscode:/home/developer/.vscode-server

 ### Rebuilding the Image
 
 `docker compose run` and `docker compose up` use the existing image — they **do not rebuild** when you change the Dockerfile or build args (e.g. updating `OPENCODE_VERSION`). Rebuild explicitly:
