 distribution should be uninstalled from your system before rustup is
 used.

+### Caveats for Windows

 On Windows, Scryer Prolog is easier to build inside a [MSYS2](https://www.msys2.org/)
 environment as some crates may require native C compilation. However,
 the resulting binary does not need MSYS2 to run. When executing Scryer in a shell, it is recommended to use a more advanced shell than mintty (the default MSYS2 shell). The [Windows Terminal](https://github.com/microsoft/terminal) works correctly.

 ### Building WebAssembly
 
 Scryer Prolog has basic WebAssembly support. You can follow `wasm-pack`'s [official instructions](https://rustwasm.github.io/docs/wasm-pack/quickstart.html) to install `wasm-pack` and build it in any way you like.
