MS SQL: Create database diagram

Today for some presentation purpose, I have to generate database diagram for a MS SQL schema. The task involves,

1. Open the SQL server management studio
2. Navigate to the Object explorer window.
3. Navigate to database folder and from the tree node select the database schema node.
4. Beneath the database schema node, find the database diagrams node.
5. Right click on the node. Click on the option create a new database design diagram.
6. Use the Add table dialog box to add existing table to the database diagram.
