+### From Source
+#### Installing Build Requirements
+
+Required components:
 * [FFTW](http://www.fftw.org/)
 * [ncursesw dev files](http://www.gnu.org/software/ncurses/) (bundled in ncurses in arch)
 * [ALSA dev files](http://alsa-project.org/)
 * [Pulseaudio dev files](http://freedesktop.org/software/pulseaudio/doxygen/)
 * libtool
+* automake
+* build-essentials
 
 Only FFTW is actually required for CAVA to compile, but for maximum usage and performance ncurses and pulseaudio and/or alsa dev files are recommended. Not sure how to get the pulseaudio dev files for other distros than debian/ubuntu or if they are bundled in pulseaudio.
