Comparing 2 documents



Hello every one!
I am a freshman, so please be kind with me.
My task is to create a page that allows to compear 2 pages of test one with another.
I was thinking of side by side comperisent, but this is the only idea I have.

Both texts are contracts. Only few terms are the same or about the same.


Hi there,
What is the purpose of making the comparison? i.e. what are people looking for? Is it edits?
