 1. Download and install [msys2](https://msys2.github.io/). Note that there are two installers-- one for 32-bit Windows systems (i386) and one for 64-bit Windows (x_64).  Make sure you know which [version](http://windows.microsoft.com/en-us/windows/32-bit-and-64-bit-windows#1TC=windows-7) of Windows you are running and download the appropriate installer.
 2. msys2 adds Start Menu items for 3 different "flavors" of shell: MinGW-w64 Win32 Shell, MinGW-w64 Win64 Shell, and MSYS Shell. Click the menu item for MinGW-w64 Win32 Shell.
 3. Once the shell opens, we need to install the dependencies for building Purr Data. Issue the following command:<code>
-pacman -S mingw-w64-i686-toolchain mingw-64-i686-fftw mingw-64-i686-libvorbis mingw-w64-i686-ladspa-sdk mingw-w64-i686-dlfcn mingw-w64-i686-lame git make autoconf automake libtool mingw-w64-i686-libsndfile mingw-w64-i686-lua</code>
+pacman -S autoconf automake git libtool \
+          make mingw-w64-i686-dlfcn mingw-w64-i686-fftw \
+          mingw-w64-i686-ladspa-sdk mingw-w64-i686-lame \
+          mingw-w64-i686-libsndfile mingw-w64-i686-libvorbis \
+          mingw-w64-i686-lua mingw-w64-i686-toolchain </code>
 4. Type `exit` in the shell and click the `Enter` key to close it, then reopen it from the menu.
 5. Download the source code. Issue the following command to create a new directory "purr-data" and clone the repository to it:<code>
 git clone https://puredata.osuosl.org/jwilkes/purr-data.git</code>
