+# (First) Demo for jumpartifact.com
+
+This project will be the demo displayed on the home page of
+[jumpartifact.com](https://jumpartifact.com).
+
+## Setting up
+
+Clone `https://github.com/emscripten-core/emsdk.git` to `${HOME}/git/emsdk`, and
+run the following commands in the cloned directory:
+
+ git checkout 3.1.44
+ ./emsdk install latest
+ ./emsdk activate latest
+
+Now you can use emsdk by sourcing the `emsdk_env.sh` file and using emcc/em++.
+The Makefile in `wasm_build/` should now "just work" with `make`.
+
+## Testing the wasm build
+
+After building the wasm version of this demo (which should have emitted an .html
+file and a .wasm file and possibly more), you can invoke `python -m http.server`
+(or use whatever http server you want) in the directory where the .html file is,
+and open your browser to `localhost:8000` (if using `python -m http.server`).
+You should then be able to click on the emitted .html to open the wasm build in
+the browser.
