 and colour behaviour the component promises. It names every case it ran and
 exits non-zero on a failure.
 
-It is run by hand against a checkout that has `react` and `react-dom`
-installed:
+```bash
+npm install
+npm test
+```
+
+`react` and `react-dom` are development dependencies, so the render has
+something to render with. Neither reaches a consuming site: that takes React
+from its own tree, through the peer dependency.
+
+Formatting and lint run over the whole tree:
 
 ```bash
-npm install --no-save react react-dom
-node test/render.mjs
+npm run format:check
+npm run lint
 ```
 
-The package declares no `test` script, and CI installs the package and stops
-there.
+CI runs all three on every pull request, and `check` is the required context on
+both branches.
 
 ## Project structure
 
 ```
 split-rail/
 ├── src/index.js         The component, its stylesheet, and the two links it carries
 ├── test/render.mjs      The markup assertions a change has to keep passing
+├── eslint.config.js     The lint rules; .prettierrc holds the formatting ones
 ├── .github/workflows/   CI (the required `check` context) and the attribution gate
 └── package.json         Exports src/index.js directly; React is a peer dependency
