sudo opkg install cheat
using the command line: install misc/cheat -- it comes with a bunch of examples on most used commands.
man pages describe the workings of commands, misc/cheat gives and collects your own examples. otherwise just search the internet for examples. write them down in a notebook or collect them in misc/cheat.
