 ## Requirements
 
 `yoga-layout` requires a toolchain that supports ES Modules and top-level await.
+
+If top-level-await is not supported, use the `yoga-layout/load` entry point instead. This requires to load yoga manually:
+
+```ts
+import {loadYoga, Align} from 'yoga-layout/load';
+
+const node = (await loadYoga).Node.create();
+node.setAlignContent(Align.Center);
+```
