Use "help" to see available commands run "cat /shellscripts" then run "sh intro.sh" to see how amazing this is :) there is a audio file, run "audio rndm.mp3" you can now add variables by doing "variable_name = value" call the variable by doing "$variable_name". you can also do "print $variable_name" you can still have characters after the variable.
I will add more commands soon. get packages at the link below If you want to make a custom package, there is a package base in the project. there is also recommended packages, like files GUI. then post your custom package here: https://scratch.mit.edu/studios/30871176/
