You have found the location of the lecture notes.
At this stage, we haven't created a menu to help you with navigating the site. However this is a RESTful site and you can easily find the notes by typing in URLs. For example if you want to find the notes for lecture 1, then after the domain type this:
/notes/1
/notes/2
... and so on.
Anyway, the actual direct links to this site are found in your LearnLine unit. One day, we'll include a neat navigation system. In the meantime use a RESTful approach.
