 You need a C++ compiler like `gcc-c++` and CMake for compiling the binary.
 
-You also need to install `libpcaudio` (`libpcaudio-dev` on Debian/Ubuntu, `pcaudiolib-devel` on Fedora/Red Hat).
+You also need to install `libpcaudio` (`libpcaudio-dev` on Debian/Ubuntu, `pcaudiolib-devel` on Fedora/Red Hat, `pcaudiolib` in Arch Linux).
 
 Then run:
 
-```
+```bash
 cmake .
 make
 ```
 
 ## How to run
 
-```
+```bash
 sudo tcpdump -n -l dst net 192.0.2.1/32 $(for a in $(cat goog-prefixes.txt); do echo or dst net $a; done)  |  ./teller 
 ```
 
 Replace `192.0.2.1` with the IP address of your default gateway (e.g. your Internet router).
 
 And then cry.
 
+### Arch Linux
+
+googerteller is available as a package in the Arch User Repository (AUR), you can install and run with the following commands:
+
+```bash
+git clone ssh://aur@aur.archlinux.org/googerteller-git.git
+cd googerteller-git
+makepkg -si
+googerteller
+```
+
 ## Problems
 
 If `tcpdump` complains about `Warning: Kernel filter failed: Cannot allocate memory`, try
 this first:
 
-```
+```bash
 sudo sysctl net.core.optmem_max=204800
 ```
