It's very simple.
Copy "images" folder, "extensions", ".htaccess" file, "LocalSettings.php" file and another added you files.
Delete MW engine folder from server, load NEW engine to server, and rewrite him previous copied files.
Start web-setup (your-site.com/mw-config/), and upgrade database.
Done.
You will have to be more specific than that Exactly which part of the manual you're having problems with?
