# No Guides
These autodocs don't contain any guide.
While the API section is a reference guide autogenerated from Zig source code,
guides are meant to be handwritten explanations that provide for example:
- how-to explanations for common use-cases
- technical documentation
- information about advanced usage patterns
You can add guides by specifying which markdown files to include
in the top level doc comment of your root file, like so:
(At the top of *${root_file_name}*)
\`\`\`
//!zig-autodoc-guide: intro.md
//!zig-autodoc-guide: quickstart.md
//!zig-autodoc-guide: advanced-docs/advanced-stuff.md
\`\`\`
You can also create sections to group guides together:
\`\`\`
//!zig-autodoc-section: CLI Usage
//!zig-autodoc-guide: cli-basics.md
//!zig-autodoc-guide: cli-advanced.md
\`\`\`
**Note that this feature is still under heavy development so expect bugs**
**and missing features!**
Happy writing!
