GLFW is a free, Open Source, multi-platform library for creating windows with OpenGL or OpenGL ES contexts and receiving many kinds of input. It is easy to integrate into existing applications and does not lay claim to the main loop.
Getting started is a guide for those new to GLFW. It takes you through how to write a small but complete program. For people coming from GLFW 2, the Moving from GLFW 2 to 3 guide explains what has changed and how to update existing code to use the new API.
There are guides for each of the various areas of the API.
The reference documentation provides more detailed information about specific functions.
There is a section on Guarantees and limitations for pointer lifetimes, reentrancy, thread safety, event order and backward and forward compatibility.
The Oculus Rift guide fills in the gaps for how to use LibOVR with GLFW.
The FAQ answers many common questions about the design, implementation and use of GLFW.
Finally, the Standards conformance guide explains what APIs, standards and protocols GLFW uses and what happens when they are not present on a given machine.
