+1. "A link to easily download a book" is not always a link to a *free* book. Please only contribute free content. Make sure it's free.
 2. You don't have to know git: if you found something of interest which is *not already in this repo*, please open an issue with your links propositions.
    - If you know git, please fork the repo and send pull requests.
 3. We have 5 kinds of lists. Choose the right one:
    - *Books* : PDF, HTML, ePub, a gitbook.io based site, a Git repo, etc.
-    - *Courses* : A course is a learning material which is not a book and where there is no interactive tool embeded in the site. [This is a course](http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/).

    - *Interactive Tutorials* : An interactive website which lets the user type code or commands and evaluates the result (by "evaluate" we don't mean "grade"). e.g.: [Try Haskell](http://tryhaskell.org), [Try Github](http://try.github.io).
    - *JavaScript Resources* : Any resources teaching a JavaScript framework or library.
    - *Problem Sets & Competitive Programming* : A website or software which lets you assess your programming skills by solving simple or complex problems, with or without code review, with or without comparing the results with other users.
