 Using [Homebrew](http://brew.sh):
 ```
-brew install openal-soft freealut libconfig
-brew install https://raw.githubusercontent.com/Tox/homebrew-tox/master/Formula/libtoxcore.rb
-brew install https://raw.githubusercontent.com/Homebrew/homebrew-x11/master/libnotify.rb

+brew install libnotify
+export PKG_CONFIG_PATH=/usr/local/opt/openal-soft/lib/pkgconfig

 ```
 
 You can omit `libnotify` if you intend to build without desktop notifications enabled.

 ## Notes
 
-<a name="comp_vars" />
 #### Compilation variables
-* You can add specific flags to the Makefile with `USER_CFLAGS=""` and/or `USER_LDFLAGS=""`
-* You can pass your own flags to the Makefile with `CFLAGS=""` and/or `LDFLAGS=""` (this will supersede the default ones)
-* Additional features are automatically enabled if all dependencies are found, but you can disable them by using special variables:
-  * `DISABLE_X11=1` → build toxic without X11 support (needed for focus tracking)
-  * `DISABLE_AV=1` → build toxic without audio call support
-  * `DISABLE_SOUND_NOTIFY=1` → build toxic without sound notifications support
-  * `DISABLE_DESKTOP_NOTIFY=1` → build toxic without desktop notifications support
+* You can add specific flags to the Makefile with `USER_CFLAGS=""` and `USER_LDFLAGS=""` passed as arguments to make, or as environment variables
+* Default compile options can be overridden by using special variables:
+  * `DISABLE_X11=1` → Disable X11 support (needed for focus tracking)
+  * `DISABLE_AV=1` → Disable audio call support
+  * `DISABLE_SOUND_NOTIFY=1` → Disable sound notifications support
+  * `DISABLE_QRCODE=1` → Disable QR exporting support
+  * `DISABLE_QRPNG=1` → Disable support for exporting QR as PNG
+  * `DISABLE_DESKTOP_NOTIFY=1` → Disable desktop notifications support
+  * `DISABLE_GAMES=1` → Disable support for games
+  * `ENABLE_PYTHON=1` → Build toxic with Python scripting support
+  * `ENABLE_RELEASE=1` → Build toxic without debug symbols and with full compiler optimizations
+  * `ENABLE_ASAN=1` → Build toxic with LLVM Address Sanitizer enabled
 
-<a name="packaging" />
-#### Packaging
-* For packaging purpose, you can use `DESTDIR=""` to specify a directory where to store installed files
-* `DESTDIR=""` can be used in addition to `PREFIX=""`:
-  * `DESTDIR=""` is meant to specify a directory where to store installed files (ex: "/tmp/build/pkg")
-  * `PREFIX=""` is meant to specify a prefix directory for binaries and data files (ex: "/usr/local")
+* `DESTDIR=""` Specifies the base install directory for binaries and data files (e.g.: DESTDIR="/tmp/build/pkg")
 
+#### Environment variables
+* You can use the `CFLAGS` and `LDFLAGS` environment variables to add specific flags to the Makefile
+* The `PREFIX` environment variable specifies a base install directory for binaries and data files. This is interchangeable with the `DESTDIR` variable, and is generally used by systems that have the `PREFIX` environment variable set by default.<br />
+**Note**: `sudo` does not preserve user environment variables by default on some systems. See the `sudoers` manual for more information.

 ## Installation
-[Use our repositories](https://wiki.tox.chat/binaries#other_linux)<br />
-[Compile it yourself](/INSTALL.md)
+[See the install instructions](/INSTALL.md)
 
 ## Settings
 Running Toxic for the first time creates an empty file called toxic.conf in your home configuration directory ("~/.config/tox" for Linux users). Adding options to this file allows you to enable auto-logging, change the time format (12/24 hour), and much more.

+=========================
+Toxic Scripting Interface
+=========================
+
+A Python scripting interface to `Toxic <https://github.com/JFreegman/toxic>`_.
+
+
+Getting Started
+===============
+Toxic is compiled with Python support by default. To access the scripting interface, simply import "toxic_api" in your script.
+
+Scripts can be run by issuing "/run <path>" from toxic, or placing them in the "autorun_path" from your toxic configuration file.
