2. Now from the MSYS2 terminal we want to install the mingw64 toolchain and the other
tools we need.
- $ pacman -S mingw-w64-i686-toolchain
- $ pacman -S base-devel
+```bash
+# choose one based on platform
+$ pacman -S mingw-w64-i686-toolchain
+$ pacman -S mingw-w64-x86_64-toolchain
-3. With that now start `mingw32_shell.bat` from where you installed MSYS2 (i.e. `C:\msys`).
+$ pacman -S base-devel
+```
+
+3. With that now start `mingw32_shell.bat` or `mingw64_shell.bat`
+ from where you installed MSYS2 (i.e. `C:\msys`). Which one you
+ choose depends on if you want 32 or 64 bit Rust.
4. From there just navigate to where you have Rust's source code, configure and build it:
$ ./configure
