 # One Container Radio
 Using Ices2 and Icecast2, the goal is to build a simple, single container deployment.  One should be able to fill few parameters and direct the container to a music folder or share giving them a basic self hosted random music stream. (Reword)
 
-** Note: Usernames / Passwords are defaulted currently.  Change them if you decide to use this... **

 ** Warning: Work in progress, Docker experimenting.  Please improve if you would like! Thanks :) **
