zdoom demos?

i know that this is probably a dumb question but, how do you make demos with zdoom?

i accidently did the wrong question. i meant "multiplayer" demos

um, try reading your documentation.
zdoom -file hr.wad -width 800 -height 600 -fullscr -nomusic -warp 1 -skill 4 -record hr2coop1 -maxdemo 4096 -net 2 68.223.42.116 +set dmflags 16 -dup 3
is an example. Your coopeative partner would do a similar thing to your IP. (note: for deathmatch, use your dmflags and altdeath nomonsters or whatever you prefer)
