 # Magnum + Qt Quick bootstrap
 
-This app demonstrates usage if Magnum rendering engine within a Qt Quick application.
+This app demonstrates Magnum rendering engine within a Qt Quick application, using
+a shared framebuffer object..
 
 ## Common pitfalls
 
 ### Header inclusion order
 
-Follow a simple rules: Always include Magnum's headers first. If you're including
-your own headers, make sure that this rules is preserved. It's very easy to violate it.

 Common symptom is compiler errors about missing declarations for `glFinish`, `glFlush`
-and `glGetError`, which some Qt headers (`QOpenGLFunctions`) are unbdefining.
+and `glGetError`, which some Qt headers (`QOpenGLFunctions`) are undefining.
 
 For a bomb-proof solution, make a header file that includes all of your Magnum and Qt
 dependencies in correct order.
