 ## Installation/removal
-For Debian-based distributives (including Ubuntu) it is recommended to call `make deb` to obtain a package that can be installed and removed with `dpkg`.
+You can use the `autorandr.py` script as a stand-alone binary. If you'd like to
+install it as a system-wide application, there is a Makefile included that also
+places some configuration files in appropriate directories such that autorandr
+is invoked automatically when a monitor is connected or removed, the system
+wakes up from suspend, or a user logs into an X11 session.
 
-On other distributives you can install autorandr by calling `make install` and remove it by calling `make uninstall`.

-If you can contribute packaging script for other distributives, we will appreciate it.
+On Arch Linux, there is [an aur package
+available](https://aur.archlinux.org/packages/autorandr-git/).

+On other distributions you can install autorandr by calling `make install` and
+remove it by calling `make uninstall`. Run `make` without arguments to obtain a
+list of what exactly will be installed.

+request if you write one.
 
 ## How to use
 
 Save your current display configuration and setup with:
-```
-autorandr --save mobile
-```
+
+    autorandr --save mobile
 
 Connect an additional display, configure your setup and save it:
-```
-autorandr --save docked
-```
+
+    autorandr --save docked
 
 Now autorandr can detect which hardware setup is active:
-```
- $ autorandr
-   mobile
-   docked (detected)
-```
+
+    $ autorandr
+      mobile

-## Apply configuration on login
-With recent versions of autorandr you typically do not need to add autorandr to `~/.xprofile`, since an autostart configuration file will be installed at `/etc/xdg/autostart/autorandr.desktop` by the makefile. It will select an appropriate profile automatically.
