Removing my cranks

Well I got a crank puller today took the dust caps off my cranks on my 36’er and now I’m stumped as to how to change the cranks… any and all advice would be very helpful because I really don’t want to damage my unicycle but I really want to put my 89mm cranks on it.

EDIT: Try this

when i put new cranks on my torker i thought they would just slide off cause thats how i put them on. turns out they didnt so i used my universal crank puller (a big pry bar) and that worked really well for me.
