+
+## 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.
+
+## Support FreeSewing: Become a patron 🥰
+
+FreeSewing is an open source project run by a community,
+and financially supported by our patrons.
+
+If you feel what we do is worthwhile, you too
+should [become a patron](https://freesewing.org/patrons/join).

+FreeSewing v2
+
+A JavaScript library for made-to-measure sewing patterns
+
+
+# bella example
+
+This project was bootstrapped with [Create Freesewing Pattern](https://en.freesewing.dev/create-freesewing-pattern):
+
+```js
+npm init freesewing-pattern
+```
+
+This example folder is part of the local development environment.
+It is **not** part of the pattern's source code.
+
+To run this example, follow these steps:
+
+ - In the folder above this one, run: `yarn start` (or `npm start`)
+ - Then, in new terminal, run the same command in this folder: `yarn start` (or `npm start`)
+
+This will spin up the development environment, similar to [our online demo](https://bella.freesewing.dev/).
