namecheap using dns.he.net anyone?

Hopefully i`m posting in the right section.
Has anyone done this?
If so, could you please help a newbie.
I`m trying to use Hurricane Electric Free DNS Management .
I bought a domain from namecheap and a vps from another company. I`d like to connect these 2 using the free dns services from Hurricane.

Is free name server for own domain? With access to zone file?

If by zone editor, you mean a place to edit/create A/AAAA/CNAME/etc then yes.
And yes its for my own domain.
