+# How to Test
+
+  - Have Rust installed via rustup.
+  - Have the wasm target installed.
+      - `rustup target add wasm32-unknown-unknown`
+  - Have `trunk` installed and in PATH.
+      - `cargo install trunk`
+  - Serve the front-end via trunk.
+      - `trunk serve`
+        - This should serve a local server at `127.0.0.1:8080`
