# Creating a Context

Before we can do anything with ModernGL we need a `Context`. The `Context` object makes us able to create OpenGL resources. ModernGL can only create headless contexts (no window), but it can also detect and use contexts from a large range of window libraries. The moderngl-window library is a good start or reference for rendering to a window.

Most of the example code here assumes a `ctx` variable exists with a headless context:

    # standalone=True makes a headless context
    ctx = moderngl.create_context(standalone=True)

Detecting an active context created by a window library is simply:

    ctx = moderngl.create_context()

More details about context creation can be found in the Context Creation section.
