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

+Last but not least, we've arrived at the level of the pattern itself.
+The pattern is a container that holds all your parts, along with the configuration
+and the store.
+
+In reality, your pattern will be a *constructor* that takes the user's settings as
+input and will return a new instance of your pattern.
+
+That pattern instance will have a `draft()` method which will do the actual work of 
+drafting the pattern. Once drafted, you can either call the `render()` method on 
+the pattern instance, or pass it to [our React component](/packages/components) to render it in the browser.
