 ## Get started
 
 Check the [Examples](https://github.com/Nuhvi/pkarr/tree/main/pkarr/examples).

+## WebAssembly support
+
+This version of Pkarr assumes that you are running Wasm in a JavaScript environment,
+and using the Relays clients, so you can't use it in Wasi for example, nor can you
+use some Wasi bindings to use the DHT directly. If you really need Wasi support, please
+open an issue on `https://git.pkarr.org`.
