There is/was a pretty comprehensive recap document about the
40k daemon codex around the intarnets and I selectively c&p'd this stuff from there. It's also good to notice that 5th ed (with the probable rending nerf) is just around corner so some of the stuff may seem odd with 4th edition in mind. I've tried to make this a bit more obscure so it's not quite "all-you-need-to-play" so it doesn't get deleted (hopefully).
The general rules:
All daemons are fearless and have
inv saves. They are also immune to
ID. No psychic powers in the list, the "psychic powers" work like innate abilites and work like normal shooting for example such as needing "to-hit" roll. At deployment, split army in half as evenly as possible and choose on half. On a 3+ you get the half you wanted. The half you got deepstrikes on turn 1 and the rest ds with normal rules (which apply to the 1st turn ds'ers too).
The meat:
HQ: Greater Daemons or 2 heralds per slot. 4 special heralds (1 for each god) and 3 special greaters daemons available.
All greaters have 4+
inv and heralds 5+, tzeentch stuff has a bit better and khorne stuff has power armor in addition.
Ld 10 all around also. Normal heralds and greaters also have a limited selection of gifts to choose. Gift price range is 5-40, most are 5-25.

Can also get marks which do the same as in Codex:
CSM, mostly around the same cost
iirc.
If marked, can get some god specific gifts in the vein of herald/greater gifts. Mostly the shooting ones, altough slaneesh prince has option for hit'n'run and the poor man's lash. The gifts cost around 5-30 barring the flight.
