 ### Storing custom data on Excalidraw elements
 
-Beyond attributes that Excalidraw elements already support, you can store `custom` data on each `element` in a `customData` object. The type of the attribute is [`Record<string, any>`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/element/types.ts#L66) and is optional.

 You can use this to add any extra information you need to keep track of.

-### Preact
-
-Since we support `umd` build ships with `react/jsx-runtime` and `react-dom/client` inlined with the package. This conflicts with `Preact` and hence the build doesn't work directly with `Preact`.
-
-However we have shipped a separate build for `Preact` so if you are using `Preact` you need to set `process.env.IS_PREACT` to `true` to use the `Preact` build.
-
-Once the above `env` variable is set, you will be able to use the package in `Preact` as well.
-
-:::info
-
-When using `vite` or any build tools, you will have to make sure the `process` is accessible as we are accessing `process.env.IS_PREACT` to decide whether to use `preact` build.
-
-Since Vite removes env variables by default, you can update the vite config to ensure its available :point_down:

-This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
-
-## Getting Started
-
-First, run the development server:
-
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
-
-Open [http://localhost:3000](http://localhost:3005) with your browser to see the result.
-
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
-
-This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
-
-## Learn More
-
-To learn more about Next.js, take a look at the following resources:
-
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
-
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
-
-## Deploy on Vercel
-
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
-
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
