  On windows you will need to have the `{architecture}-pc-windows-msvc` toolchain
  installed as well as [Clang 3.9 or greater](http://releases.llvm.org/download.html).
  +#### Clear Linux
  +
  +On Clear Linux, you need a few extra libraries to build Alacritty. Here's a
  +`swupd` command that should install all of them. If something is still found
  +to be missing, please open an issue.
  +
  +```sh
  +swupd bundle-add devpkg-expat devpkg-freetype devpkg-libxcb
  +```

  #### Other
  If you build Alacritty on another distribution, we would love some help
