Put the folder course_menu inside your moodle/blocks directory and visit your admin page. 

Put the lang files in your lang directory. 

If you install block_quickmail_1.5, an 'Email students' link will show up in the control panel.

If you install block_course_program, links for setting course visibility dates and due dates will show up in your control panel. 

If you don't install these blocks, they won't show up and the control panel will function fine without them.

Let us know if you have any problems.
