This is like many textbased games, so it requires... well, atleast some basics.
That is like..
"Look" (west east north south up down)
"Walk" (west east north south up down)
"say" (your text)
"Kill" (whenever there is a creature in your current location)
"stats"
"skills"
"experience"
"inventory"
"eat"
"drink"
and most importantly "flee" haha!
That should get you started.

There is "buy" and everything aswell.
Just type "help".
