 ### 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/src/element/types.ts#L66) and is optional.

-### Static assets
+### Self-hosting fonts
 
-Excalidraw depends on assets such as localization files (if you opt to use them), fonts, and others.
+By default, Excalidraw will try to download all the used fonts from the [CDN](https://esm.run/@excalidraw/excalidraw/dist/prod).
 
-By default these assets are loaded from a public CDN [`https://unpkg.com/@excalidraw/excalidraw/dist/`](https://unpkg.com/@excalidraw/excalidraw/dist), so you don't need to do anything on your end.
-
-However, if you want to host these files yourself, you can find them in your `node_modules/@excalidraw/excalidraw/dist` directory, in folders `excalidraw-assets` (for production) and `excalidraw-assets-dev` (for development).
-
-Copy these folders to your static assets directory, and add a `window.EXCALIDRAW_ASSET_PATH` variable in your `index.html` or `index.js` entry file pointing to your public assets path (relative). For example, if you serve your assets from the root of your hostname, you would do:
+For self-hosting purposes, you'll have to copy the content of the folder `node_modules/@excalidraw/excalidraw/dist/prod/fonts` to the path where your assets should be served from (i.e. `public/` directory in your project). In that case, you should also set `window.EXCALIDRAW_ASSET_PATH` to the very same path, i.e. `/` in case it's in the root:
 
 ```js
 window.EXCALIDRAW_ASSET_PATH = "/";
 ```
 
+or, if you serve your assets from the root of your CDN, you would do:
+
+```js
+// Vanilla
+<head>
+    <script>
+        window.EXCALIDRAW_ASSET_PATH = "https://my.cdn.com/assets/";
+    </script>    
+</head>
+```
+
+or, if you prefer the path to be dynamicly set based on the `location.origin`, you could do the following:
+
+```jsx
+// Next.js
+<Script id="load-env-variables" strategy="beforeInteractive" >
+    { `window["EXCALIDRAW_ASSET_PATH"] = location.origin;` } // or use just "/"!
+</Script>

 Excalidraw takes _100%_ of `width` and `height` of the containing block so make sure the container in which you render Excalidraw has non zero dimensions.

+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.
