+### Workflows
+
+Pre-built multi-agent workflow definitions in `workflows/<name>.toml` orchestrate multiple agents for complex tasks.
+
+**9 workflows:** brainstorm, code-review, content-pipeline, content-review, customer-support, data-pipeline, research, translate-polish, weekly-report
+
+### Templates
+
+Starter templates in `templates/` for creating new content. Copy a template to get started quickly:
+
+```bash
+cp templates/agent.toml agents/my-agent/agent.toml
+cp templates/HAND.toml hands/my-hand/HAND.toml
+```
+
+**6 templates:** agent.toml, HAND.toml, integration.toml, plugin.toml, provider.toml, skill.toml
+
+See also [docs/content-guide.md](docs/content-guide.md) for naming conventions and contribution guidelines.
