 - `no-undeclared-dependencies`: imported packages are declared in the nearest `package.json`. `devDependencies` are only allowed with the `allowDevDependencies` option, for example in tests. Type-only imports are skipped.
 - `organize-imports`: imports are grouped by builtin, external, parent, sibling and index modules, then other paths like tsconfig aliases, and sorted alphabetically within each group. Side-effect imports stay in place. Fixable.
 - `test-root-describe`: the root `describe` of a spec file is named after its path, without `src/`, `lib/` or `test/` and the `.spec.ts` suffix. Fixable.

+## Development
+
+Node.js, pnpm and jactionlint are pinned in [`mise.toml`](./mise.toml), so [`mise`](https://mise.jdx.dev) installs them and the dependencies with `mise install`.
+Without mise, install the dependencies with `pnpm install`.
+
+```bash
+mise install
+pnpm lint
+pnpm test
+pnpm build
+jactionlint
+```
+
+- `pnpm lint-fix` fixes the formatting and the fixable lint findings.
+- `pnpm build` compiles the plugin to `dist/`, which is what the package ships.
+- `jactionlint` checks the GitHub workflows.
