+ ** Command list for Melon's shell **
+
+ Command Description Required groups
+ - help shows this
+ - reboot reboots your computer root
+ - halt shuts down your computer root
+ - loadkeys loads a new keymap root
+ - free shows free amount of RAM
+ - uptime shows computer's uptime
+ - run runs a binary file
+ - wf writes text to a file
+
+The shell also supports basic UNIX-like commands :
+ ls, cd, cat, pwd, rm, mkdir
+
+The terminal supports scrolling with shift+{up,pgdown,pgup}
