-### Desktop Usage
+### Desktop Installation
 
-#### Recommended Binaries for OS X Users
+Hack is available for download in either [OTF][otf_latest] or [TTF][ttf_latest] formats. The best format and install approach depends on your operating system. If you do not know which format is optimal for your system, the TTF files should be used as your default.
 
-The .otf or .ttf files may be used on OS X platforms.
+Because Hack is under active development and updates are released frequently we highly recommended using a package manager or other auto-updating utility.  While the package manager releases may be a bit delayed relative to the repository releases, the package managers automate and simplify font updates on your system.  Please note that the Hack packages in these package managers are not maintained by the Hack project developers.  If you come across a problem with the release schedule in your package manager, please report it directly to the respective package maintainer on your platform.

+#### OS X
 
-#### Recommended Binaries for Linux and Windows Users
+The easiest way to install and update Hack on OS X is to use the [Homebrew](http://brew.sh/) package manager. To install the fonts on OS X use the command:
 
-The .ttf files are recommended for screen use on Linux and Windows platforms.
+    $ brew cask install caskroom/fonts/font-hack

+To install the fonts manually you may use either the [OTF][otf_latest] or [TTF][ttf_latest] formats. Download the zip file and extract it. Double clicking each of the font files will open a preview in [Font Book](https://support.apple.com/en-us/HT201749) and the "Install Font" button will copy the font to the correct system location.
+
+#### Linux / BSD
+
+Most Linux and BSD systems can handle either [TTF][ttf_latest] or [OTF][otf_latest] format fonts. We are aware of package manager support on the following distros:
+
+* *Arch Linux*: install the [ttf-hack](https://www.archlinux.org/packages/community/any/ttf-hack/) package from the community repository ([otf-hack](https://aur.archlinux.org/packages/otf-hack/) is available in the AUR):
+
+        $ pacman -S ttf-hack
+
+* *Fedora / CentOS*: install from [copr](https://copr.fedoraproject.org/coprs/heliocastro/hack-fonts/). For Fedora >= 23:
+
+        $ dnf install dnf-plugins-core
+        $ dnf copr enable heliocastro/hack-fonts
+        $ dnf install hack-fonts
+
+  For Fedora <= 22 and CentOS <= 7:
+
+        $ yum install yum-plugin-copr
+        $ yum copr enable heliocastro/hack-fonts
+
+* *Ubuntu / Debian*: install either [fonts-hack-ttf](http://packages.ubuntu.com/xenial/fonts-hack-ttf) or [fonts-hack-otf](http://packages.ubuntu.com/xenial/fonts-hack-otf). Packages are currently available for Ubuntu Xenial or later and the Debian unstable branch:
+
+        $ apt-get install fonts-hack-ttf
+
+   For older systems either manually download and install one of the deb packages or see the [manual install instructions](https://wiki.ubuntu.com/Fonts).
+
+For other systems, check for packages using your distro's package manager search function. If no packages exist download your preferred format and copy the font files to either your system font folder (often `/usr/share/fonts/`) or user font folder (often `~/.local/share/fonts/`). On systems using Fontconfig you may need to regenerate the font caches and indexes after copying the files (e.g. `fc-cache -s; mkfontscale <install_path>; mkfontdir <install_path>`).
+
+
+#### Windows
+
+On Windows, the [TTF][ttf_latest] format files are recommended. Download the zip, extract the files, and double click on them to open them in the font previewer. Clicking the "Install" button will then copy them to the correct place on your system.
