- [Images and videos](https://contributors.home-assistant.io/writing/reference/images/): add screenshots, diagrams, and videos, and describe them for every reader.
- [Liquid helpers](https://contributors.home-assistant.io/writing/reference/liquid/): every Liquid tag home-assistant.io adds on top of Markdown.
- [YAML style](https://contributors.home-assistant.io/writing/reference/yaml/): how YAML examples should look.
- [Automated documentation checks](https://contributors.home-assistant.io/writing/reference/checks/): what the checks on your pull request look for, and how to run them yourself.
- [Integration front matter](https://contributors.home-assistant.io/writing/reference/front-matter/): every key at the top of an integration page.
- [Integration page structure](https://contributors.home-assistant.io/writing/reference/integration-page/): the sections of an integration page, and the blocks that fill them.
