 # abbiefetch
 abbiefetch is a POSIX compliant fetch script intended to be as portable as possible to run on machines of any age. abbiefetch is not dependent on any specific shell and should run fine on any system with a POSIX compliant shell and Unix utilities.
 
+## Building
+To build abbiefetch, clone this repository and run `./build.sh`. If you receive errors about `tee` having an invalid option then run `./build_alternate.sh`.
+
 ## Compatibility
 abbiefetch will attempt to gather as much information as possible on systems that don't have full compatibility and will provide you with a system type (and sometimes a subtype) to let you know what abbiefetch thinks your computer is running.
