Instructy Design is a design community to find and share the best design courses & tutorials. Design community upvotes the design tutorials they have found useful, and hence best tutorials rise to the top of the page.
Almost the entire digital design and print design discipline has been covered in the platform. Plus the people behind this are the makers of hackr.io- which a similar collection of tutorials for Programming languages. Hope to see more such things from them.
A really good collection of tutorials, most of them being free.
