-### 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>
+```
+
 ### Dimensions of Excalidraw
 
 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.
