The replaces the NextJS site powering FreeSewing.dev with a Docusaurus
setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: "The part's draft method"
+---
+
+Each part **must** have a `draft` property that holds a method that will draft the part.
+In other words, this method is where the actual work happens. The method's signature
+is as follows:
+
+```js
+function draft(props)
+```
+
+The draft method receives a single parameter, an object which you can _destructure_ to
+access the following properties:
+
+| Property | Description |

+| `Point`           | A [Point constructor](/reference/api/point) to create new points |
+| `Snippet`         | A [Snippet constructor](/reference/api/snippet) to create new snippets |
+|| **_Content containers_** |
+| `paths`           | Add a Path to your part by adding it to this object |

+Instead, optional measurements are accessed via the 'measurements'
+property.
