# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to

OC White Boom - http://www.ocwhite.com/broadcast-arms/proboomtm-elite-extended-reach-mic-arm-with-riser-45-reach-12-vertical-riser.html

The kit comes with a boom. It is decent, I guess, but this OC White boom is badass prostyle with a 4' reach and a 15" riser that lets it live behind my monitor.
