How to elegantly make reference when the whole section is a summary of other people's work?

I understand the basic rule that I should always put original sentence in the quotation mark and give a reference to the source. However, what if I dedicate the whole section to the summary of somebody else's work?

The section will looks like this by strictly abiding the rule:

John proposed a solution to this problem in 2008 (John, 2008). To solve this problem, he introduced an approach based on "bla bla bla" (John, 2008). The basic idea is that he developed a four-stage process to address the problem: Stage1, Stage2, Stage3, Stage4 (John, 2008).

Stage1 is "bla bla bla...." (John, 2008), which is important in the whole approach.

Stage2 is "bla bla bla....", in which "bla bla bla" (John, 2008). ... ...

So is there an elegant way to write it?
