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: sample()
+---
+
+```js
+Pattern pattern.sample()
+``` 
+
+This method calls either [sampleOption()](#sampleoption), 
+[sampleMeasurement()](#samplemeasurement), 
+or [sampleModels()](#samplemodels).
+
+Unlike those three methods who you need to pass the relevant info to, 
+[sample()](#pattern-sample) will read the `pattern.settings.sample` 
+object to determine what to do.
+
+The possiblities are:
+
+ - **type**: One of `option`, `measurement`, or `models`
+ - **option**: An option name as defined in the pattern config file (only used when `type` is option).
+ - **measurement**: A measurement name as defined in the pattern config file (only used when `type` is measurement).
+ - **models**: An array of models with the required measurements for this pattern (only used when `type` is models).
+
+See the specific sample methods below for more details.
+
+<Tip>
+
+###### Anchor your samples
+
+If you add a point named `anchor` to your pattern part, the different samples
+will be anchored on this point.
+
+In other words, for each sample, the anchor point will be kept in the same location.
