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: Create a new folder for the blog post
+order: 10
+---
+
+Our [markdown repository](https://github.com/freesewing/markdown/) holds all content
+for both freesewing.org and freesewing.dev.
+
+The content for blog posts on freesewing.org is in the `org/blog` folder.
+
+You'll find a bunch of directories here for all the existing blog posts. 
+Create a new one keeping in mind that this will determine the URL under which the post
+is available. So:
+
+ - No spaces
+ - No uppercase
+ - Stick to `a-z` and `-` to be safe
