-### Installation
-As mentioned at the beginning of this file, `bc` is a requirement to running, along with a few other common shell utilities.
-While it is possible to simply clone this git repositiory and simply run `./pizza.sh`, one might be interested in a system wide installation. 
-In that case, the recommended install instructions are as follows:
-```
-sudo su
-cd /usr/local/share/
-git clone https://git.skeh.site/ida/pizzacalc.git
-ln -s /usr/local/share/pizzacalc/pizza.sh /usr/local/bin/pizza
-```
-(Most GNU/Linux distributions will already have /usr/local/bin/ in their paths.)
