+# Contributing a new demo
+
+## Preface
+
+Thanks for being interested in contributing a demo! Before you read more, have you read the [contribution guide](https://github.com/pmndrs/react-spring/blob/master/CONTRIBUTING.md) for the repo? If not, give it a look first!
+
+## What is required
+
+All our demos are based on codesandbox templates for react-typescript. If you're going to contribute a
+demo, you can either copy an existing demo and tweak it or create a new one in codesandbox, export the
+code and add it to the repo.
+
+You should ensure your demo follows the same structure as the other ones:
+
+```
+- public
+- src
+- - App.tsx
+- - index.tsx
+- .pretterrc
+- package.json
+- tsconfig.json // I would copy this from an existing one
+- thumbnail.png
+```
+
+This is the minimum we require as the `App.tsx` is used to integrate with our demo hub via vite in the repo.
+
+A few other things to remember
+
+### Thumbnail
+
+This should be included to showcase your work best! Make sure it's a 16:9 ratio.
+
+### Package.json
+
+Ensure there's a clear name and description as these appear on the website. You should also use `tags` to highlight keywords
+especially the `react-spring` hooks you've used.
+
+## When you're ready
+
+When you've finished adding your code, open a PR explaining the example, why you think it should be included
+and most importantly, include a sandbox link so it can be looked at and admired!
