-To start them you should enter to a directory of any and start it
-with [cargo-web]:
+To run them you need to have [cargo-web] installed as well as a suitable target
+for the Rust compiler to generate web output. By default cargo-web uses
+`asmjs-unknown-emscripten`. Install cargo-web and the asmjs emscripten target
+as follows:
