How can i start a good Chaos Daemons army?

Daemons are a hard army to start unless you've got a pretty large amount of cash. First of all you need a codex, second fill out your compulsory with your HQ and 2 troops. You need to read through your codex and experiment on the kind of daemons you want, Nurgle, Tzneetch, Khorne, Slanesh. Each have their own advantages and disadvantages, keep in mind a daemon army has almost no shooting ability, so your gonna be trying to get up close, fast.
