Can someone tell me how to map?

Well, I’ve tried Source SDK but when I click Hammer Editor it tells me I need to configure something.
Can someone tell me the settings and stuff?

Im using
Engine Version: HalfLife2- Ep 1
Current Game: Counter-Strike Source

Im looked on youtube, But I dont have HL2: DeathMatch so :S



I’m sure if you look around on google than you can figure out how to get it set up, I’ve found it somewhere before. If I find it again I’ll post a link with the directions on how to set it up for you. Other than that, Hl2: DM is only 5$ so it wouldn’t be too bad to go with that route if all else fails.

Eh, Maybe
