+This is a UNIX terminal emulator.
+Most of the basic unix commands are available (ls, cat, rm, mkdir, etc)
+
+Although you may not be a unix user so heres a quick summary what command does what:
+ls \t- List files in directory
+cat \t- Read file contents to terminal
+rm \t- Remove file contents
+mkdir \t- Create directory
+wget \t- Download file from internet (more: wget --help)
+ps \t- List processes
+l \t- alias to ls -al
+
+Also there are some custom defined commands which are somewhat more fun:
+guide \t- Show you this menu
+skills \t- My skills info
