+## What am I looking at? 🤔
+
+This repository is our _monorepo_ holding [all our NPM packages](https://www.npmjs.com/search?q=keywords:freesewing).
+This folder holds **@freesewing/plugin-measurements**
+
+A FreeSewing plugin that adds additional measurements that can be calculated from existing ones
+
+## About FreeSewing 💀
+
+Where the world of makers and developers collide, that's where you'll find FreeSewing.
+
+Our [core library](https://freesewing.dev/reference/api/) is a _batteries-included_ toolbox
+for parametric design of sewing patterns. It's a modular system (check our list
+of [plugins](https://freesewing.dev/reference/plugins/) and getting started is as simple as:
+
+```bash
+npm init freesewing-pattern
+```
+
+The [getting started](https://freesewing.dev/guides/getting-started/) section on [freesewing.dev](https://freesewing.dev/) is a good
+entrypoint to our documentation, but you'll find a lot more there, including
+our [API reference](https://freesewing.dev/reference/api/),
+as well as [our turorial](https://freesewing.dev/tutorials/pattern-design/),
+and [howtos](https://freesewing.dev/howtos/).
+
+If you're a maker, checkout [freesewing.org](https://freesewing/) where you can generate
+our sewing patterns adapted to your measurements.
+
