+# Reference
+
+This section contains reference material for using `wasm-bindgen`. It is not
+intended to be read start to finish. Instead, it aims to quickly answer
+questions like:
+
+* Is type X supported as a parameter in a Rust function exported to JavaScript?
+
+* What was that CLI flag to disable ECMAScript modules output, and instead
+  attach the JavaScript bindings directly to `window`?
