+#### mymonero-core-js (optional)
+
+OpenMonero uses frontend code provided by mymonero.com. Among many files
+used, the two crtical ones are binary webassamply
+[MyMoneroCoreCpp_WASM.wasm](https://mymonero.com/js/lib/mymonero_core_js/monero_utils/MyMoneroCoreCpp_WASM.wasm) and
+the corresponding JavaScript [mymonero-core.js](https://mymonero.com/js/lib/mymonero-core.js) files.
+They are used by [send_coins.js](https://mymonero.com/js/controllers/send_coins.js?) for providing
+transaction generation functionality.
+
+OpenMonero provides these files here: `./html/js/lib`. They were generated using forked of the mymonero-core-js repo:
+https://github.com/moneroexamples/mymonero-core-js/tree/openmonero
+
+However, you can compile them yourself using their orginal repository at
+https://github.com/mymonero/mymonero-core-js.
+
+Below are instructions on how it can be done on Arch Linux.
+
+```
+git clone https://github.com/mymonero/mymonero-core-js.git
+
+cd mymonero-core-js/
+
+./bin/update_submodules
+
+npm install
+
+# download boost
+wget -c "https://dl.bintray.com/boostorg/release/1.68.0/source/boost_1_68_0.tar.gz" -O /tmp/boost.tar.gz && mkdir -p ./contrib && tar xzvf /tmp/boost.tar.gz -C ./contrib && mv ./contrib/boost_1_68_0/ ./contrib/boost-sdk
+
+# set EMSCRIPTEN paths (for this, you need to have EMSCRIPTEN setup, e.g. in your home folder)
+# http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
+source ~/emsdk/emsdk_env.sh
+
+# compile boost
+./bin/build-boost-emscripten.sh
+
+# compile mymonero-core-js
+./bin/build-emcpp.sh
+
+# generate mymonero-core.js
+./bin/package_browser_js
+
+```
+
+The above instructions should produce `mymonero-core.js`
+and `mymonero_core_js/monero_utils/MyMoneroCoreCpp_WASM.wasm`
+(both located in `./build` folder), which can
+be used in place the files bundled with OpenMonero.
