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: Part dependencies
+---
+
+Part dependencies control the order in which parts are drafted. FreeSewing will
+make sure to draft all of a part's dependencies before drafting the part
+itself.
+
+:::warning
+Even though inherited parts are automatically included in a part's dependencies,
+do not confuse part dependencies with [part inheritance](/howtos/code/from).
+
+:::
+
+Part dependencies are configured with [the `after`
+keyword](/reference/api/part/config/dependencies#after). Let's look at an
+example:
+
+```js
+// highlight-start
+import { otherPart } from './otherpart.mjs'
+// highlight-end
+
+export const myPart = {
+  name: 'example.myPart',
+// highlight-start
+  after: otherPart,
+// highlight-end
+  draft: function ({ part }) {
+    // Design part here
+    return part
+  }
+}
+```
+
+:::tip
+Refer to [the part documentation on
+dependencies](/reference/api/part/config/dependencies) for all details.
