 ## Commands
 
-All `npm` commands must be run inside Docker containers. Use `node_shell` for most tasks, `playwright` for visual tests.
+All commands below are meant to be run directly inside the Docker container `devcontainer`.
+If you open the project in a Dev Container, you can run these commands without manually
+starting Docker Compose on the host.
 
-```bash
-# Enter node_shell container
-docker compose run --rm node_shell
-
-# Enter playwright container (for visual tests)
-docker compose run --rm --service-ports playwright
-```
-
-**Within `node_shell`:**
 
 ```bash
 npm run lint                          # All linters (ESLint + Stylelint + Markdownlint)
