+## Example usage of matrix-rust-sdk from WASM
+
+You can build the example locally with:
+
+    npm install
+    npm run serve
+
+and then visiting http://localhost:8080 in a browser should run the example!
+
+Note: Encryption isn't supported yet
+
+This example is loosely based off of [this example](https://github.com/seanmonstar/reqwest/tree/master/examples/wasm_github_fetch), an example usage of `fetch` from `wasm-bindgen`.
