+## Development
+
+WebAssembly port of Monolith is developed in [the forked repository][4]. Currently it has some differences
+and duplicates against the original repository. reqwest did not support Wasm before 0.10.0 so my Wasm
+port does not use it and uses `fetch()` directly via `js_sys` and `web_sys` crate.
+
+This repository adds the forked Monolith repository as a Git submodule and uses it by bundling sources
+with Webpack.
