The method involves limiting the enemy King to less and less space by
using the rook and king together. As an illustration take the position:

	White
	Ke1, Ra1

	Black
	Ke8

	White to move.

1. Ra7 

This move limits the Black king to the last rank. The technique now
involves keeping him there and hemming him in, while the black king
attacks the rook.

1 ... Kd8
2. Ke2

Begin to bring the king up in order to coordinate the attack.

2. ... Kc8
3. Ke3 Kb8

Attacking the rook

4. Rh8 Kc8
5. Ke4 Kd8
6. Ke5 Ke8
7. Kf6

Now here we have the beginning of some forcing moves for if 7 ... Kf8,
then Rh8 mates. So,

7. ... Kd8

The black king attempts to flee, but alas is hopeless 

8. Ke6

Again the same forcing idea for if 8 ... Ke8, then Rh8 mates.

8. ... Kc8
9. Kd6 Kb8
10. Kc6 Ka8
11. Kb6 Kb8
12. Rh8 ++
1-0 Black is checkmated

There are of course even fancier methods of doing it where a rook lift
is employed to gain a temp and force the king into the corner, but the
above illustration should do the trick.
