I'm doing some research on how to improve/make appleseed[1] documentation. Appleseed is an open-source rendering software and we need both user and developer documentations such as: - Guide on how to use appleseed - Detailed docs on how appleseed is working - Developer documentation (API reference, contribution guide, getting started)

So if there is a documentation that you really like, please share it :)(whether it's about rendering or not, for user and/or for developers)
