Sometimes, I find that when the end of one of my sentences is too long, the whole sentence should be tightened. I like to think of my text as a tweet that must convey everything with no characters wasted.
Thus, in your case, I came up with:
Revising Prose explores how to write clearer and concise writing.
I took out "simpler" as I felt that was implied.
Then I considered that "explores how to" has a single word replacement:
Revising Prose demonstrates writing clearer, concise writing.
Which it should not take a genius to realise is a horrible sentence with needless repetition. Thus I went further:
Revising Prose examines concise and clearer writing.
19 words reduced to 7.
If this was me, I would now move on to talking about the tutorials.
