I really liked this paper by Neil Strickland. It's quite good, but it only really covers the affine case. Be forewarned that, as stated in the introduction, scheme is taken to mean affine scheme unless explicitly noted.

Be forewarned that, as stated in the introduction, scheme is taken to mean affine scheme unless explicitly noted. A very nice thing about the approach of this paper is that it works without many/any finiteness assumptions (since these often cannot be assumed for algebro-topological or homotopy-theoretic applications).
