dnssec keys how to

Hello,

I have enabled dnssec in Directadmin.
at my provider I can add dnssec keys, but I have no idea what exactly to fill in.
Do I have to add KSK and ZSK both or only the key for KSK?
Witch algorithm do I have to set?

Key tag: I assume the Key ID
Algorithm ?
Flags_ KSK or ZSK or both?
