The test command format is inconsistent with other commands in the list. Lines 13-18 all use bun run, but lines 11-12 do not. Additionally, to match the behavior defined in package.json, use bun run test (which runs bun test --coverage) and bun run test:watch instead.

Suggested change

	- `bun test` - Run tests
	- `bun test --watch` - Watch mode
	- `bun run test` - Run tests with coverage
	- `bun run test:watch` - Watch mode

The docs/guide/ directory exists and contains important setup documentation (installation.md and your-first-rule.md) but is not listed in the User-Facing Documentation section. Add docs/guide/ to this section to help developers find setup and workflow guidance.

Suggested change

	- `docs/concepts/` - Rules, conditions, actions, templates (domain model)
	- `docs/concepts/` - Rules, conditions, actions, templates (domain model)
	- `docs/guide/` - Setup and workflow guidance, including installation and your first rule
