Review on Gitbook by Carlos Long

It's easy to use as it has an intuitive interface that allows you to navigate between sections quickly. The best part is we can customize our content in multiple ways. You can add new pages/sections/chapters by simply dragging & dropping different components from toolbox. We are using gitbook to create various kinds of technical docs like API reference guides, SDKs etc. So far I haven't found anything that would be disliking about this product. If your looking into creating some kind of a doc then definitely give it a try since its free to download & open-source.
