# Parcel format v1

Sample project documentation. Parcel is a format defined for this example, not an installed package or external service.

## Quickstart

Create a UTF-8 JSON document with `project` and `files`. Open `index.html` and use the playground to validate it.

```json
{"project":"Harbor identity","files":[{"path":"brand-guide.pdf","label":"Brand guide"}]}
```

## Reference

- `project`: non-empty string.
- `files`: array with at least one entry.
- `files[].path`: non-empty relative path with forward slashes. No backslashes, colons, query strings, fragments, empty segments, `.` or `..` segments. Paths must be unique.
- `files[].label`: non-empty string.

Unknown fields are allowed. The playground checks structure and path syntax only, not file existence. The PDF in this example is a representative filename, not a bundled document.

## Navigation

Direct chapter links use `#quickstart`, `#reference`, and `#validation`. They work on a static file host and survive reloads.
