Welcome to the site Bowge. As EricMina stated (thank you Eric), there is an intro lesson for those with only the C Harmonica, and it's found here http://www.bluesharmonica.com/lessons/c_harmonica_intro_lesson. After this lesson, if you decide to continue, you'll need to pick up an A Harmonica. Best wishes on your studies.
David might be busy with a student so I'm gonna reply just so you get started. Hope you don't mind David.
Heres a link for the level 1 in C.
