In Hebrew, Deuteronomy means “Second Law” the entire book contains the three addresses Moses gave, which he charged to be composed upon stones. In these addresses, Moses helped the general population to remember every one of the things that God did for them. Likewise helping them to remember every one of the necessities to be met for the gifts God needed to provide for His kin.
In Moses' Second sermon in Deuteronomy, he seeks to invoke covenant renewal on the part of the second generation by reminding them of what God did for Israel. He gives instructions to the new generation in hopes to help them to repent of the rebelious ways of their parents and be able to receive the blessings and guidance from God. He reviews the laws of the covenant, with all the ordinances and the blessings attached to them. If they continue being faithful and loving God above all, He will bless them.
