 ## Installation
 
-The installation of WRF-CMake or WPS-CMake is straightforward thanks to the downloadable pre-built binaries for most Linux distributions (specifically [ RPM-based and Debian-based distribution-compatible](https://en.wikipedia.org/wiki/List_of_Linux_distributions)), macOS, and Windows (see [binary distribution](#binary-distribution-experimental) below) -- most users wishing to run WRF on their system can simply download the pre-compiled binaries without the need of building from source. Alternately, you can install WRF-CMake or WPS-CMake using the Homebrew/Linuxbrew package manager or by building and installing the software from source, please refer to the build and install [manually from source](#manually-from-source) and [Using Homebrew or Linuxbrew](using-homebrew-or-linuxbrew) section below.
