Zeal is an offline documentation browser that is designed for developers.
It is a great tool for folks who read and refer often to documentation.
Having documentation offline can be a big time saver.
I have Zeal installed on every computer I use, so I could quickly read more about a certain function or module for Python.
I find it extremely helpful and believe you might find it the same if you have not used it already.
