feat: Flat import of markdown repo

This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown

+title: Structure of a part
+order: 150
+---
+
+Let's get rid of the example box first.
+Open `src/bib.js` and make sure it looks like this:
+
+```js
+export default function(part) {
+  let { Point, points, Path, paths } = part.shorthand();
+  // Design pattern here
+
+  // Complete?
+  if (complete) {
+    if (sa) {
+    }
+    // Paperless?
+    if (paperless) {
+    }
+  }
+  return part;
+}
+```
+
+This is an empty skeleton for a pattern part. Anytime you want to create a new part,
+this is a good starting point.
+
+Let's quickly go over the different sections.
+Even if there's not much going on yet, it's always good to understand what's going on.
+
+## The draft method
+
+```js
+export default function(part) {
+
+  // ...
+  
+  return part;
+}
+
+```
+
+This is the boilerplate of our `draftBib` method. It takes the part as an argument, and returns it.
+
+<Note>
+
+If you're new to JavaScript, and don't intuitively *get this*, stick with it. It will become second nature soon enough.
+
+</Note>
+
+## Using shorthand
+
+```js
+let {
+  Point,
+  points,
+  Path,
+  paths,
+} = part.shorthand();
+```
+
+This is FreeSewing's **shorthand** method. It returns an object with a bunch of handy helpers
+and you use JavaScript's *object destructuring* to only get what you need.
+
+The example above makes the following variables available:
+
+ - `Point`: The Point constructor
+ - `points`: A reference to the part's points
+ - `Path`: The Path constructor
+ - `paths`: A reference to the part's paths
+
+<Note>
+
+This will all become clear, but if you're curious, the API docs have all the details 
+on [the Part.shorthand() method](/reference/api/part/#shorthand)
+
+</Note>
+
+## Part boilerplate
+
+```js
+// Complete?
+if (complete) {
+  if (sa) {
+  }
+  // Paperless?
+  if (paperless) {
+  }
+}
+```
+
+This is some more boilerplate that makes sure we respect the `complete`, `sa`, and `paperless` settings.
+
+For now, you don't need to worry about this. Let's just start designing our bib.
