 No frills. No gimmicks. Hack is hand groomed and optically balanced to be a workhorse face for code. It has deep roots in the libre, open source typeface community and expands upon the contributions of the [Bitstream Vera](https://www.gnome.org/fonts/) & [DejaVu](http://dejavu-fonts.org/wiki/Main_Page) projects.

 ## Advanced options
 
-<!-- TODO intro about updates -->
+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.
 
-A full list of all changes can be found in the [CHANGELOG](docs/CHANGELOG.md).
+### Package managers and desktop installation
 
-### Advanced installation options
+Details on using package managers and/or advanced manual desktop installation options can be found in [INSTALLATION.md](docs/INSTALLATION.md).
 
-<!-- TODO installation, package managers (intro + link) -->
+Hack can be installed and updated via various package managers. We are aware of package manager support on the following systems/distros:
 
-### Web font usage
+- **Mac OS X**: `homebrew`
+- **Arch Linux**: `pacman`
+- **Fedora / CentOS**: `copr`, `dnf` or `yum`
+- **Gentoo Linux**: `emerge`
+- **Ubuntu / Debian**: `apt-get`
 
-<!-- TODO web font usage (intro + link) -->

-### Additional tools for customization
+<!-- TODO @chris: no idea if the wording of the above makes any sense for package manager users -->
 
-<!-- TODO add a bit about font-line -->
+### Web font usage
 
+Hack is available in all the regular webfont formats. See [WEBFONT_USAGE.md](docs/WEBFONT_USAGE.md) for more details, or use the snippets below to quickly include Hack via a CDN by the generous gang at [jsDelivr](https://github.com/jsdelivr/jsdelivr). **Bold** and _italic_ styles are included by default and work out-of-the-box via the `<strong>` and `<em>` tags.

-You can now modify the default line spacing in Hack fonts with our new `font-line` tool.  Hack uses a default value of 20% UPM for line spacing.  Decrease the value to tighten the spacing, increase it to widen your spacing.  Modification details are available on the `font-line` repository:
+```css
+code {
+	font-family: Hack, monospace;
+}
+```

+### Additional tools for customization
 
-or [use one of our handy shell scripts](https://github.com/chrissimpkins/Hack/tree/master/tools/line-spacing) that automates the `font-line` install and line spacing modification process for a range of line spacing % UPM values between 10 - 30%.  Select the script that fits your needs and execute it in the download directory that contains your .ttf and/or .otf font files **before you install them**.
