 # ukebox

 `ukebox` is a command-line tool that shows you how to play a given chord on a ukulele by printing a chord diagram in ASCII art.
 
 ## Installation
 
-`ukebox` is intended to be a stand-alone command-line application but for the time being you need Rust (version >= 1.37.0) to build and run the program. Get the source code by cloning the repo from Github.
