-## Using TypeScript
+## Requirements
 
-This package provides out-of-the-box TypeScript typings so long as `tsc` is configured to support ESM resolution. It is recommended to set `moduleResolution: 'bundler'` or `moduleResolution: node16` in your `tsconfig.json` according to your environment.
-
-## ES Modules
-
-`yoga-layout` is only provided as an ES Module, relying on top-level await. This allows providing a synchronous API, while still allowing async WebAssembly compilation in browsers, and will allow eventual usage of ESM/WASM interop.
