How to change an HTML 4 document to HTML 5?

Question:

I have a ready-made project, made in HTML 4.01, how can I change it so that it recognizes HTML 5 ?

I can just change this:

 < !DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd" >

for:

< !DOCTYPE html >

and will it work?

Answer:

Exactly, this is the correct way. This form makes the code compatible with HTML 5 and earlier versions.
