title: How do you add GPUImage to an iOS project?
body: <p>I am trying to make a camera/photo app that will add a filter on an image. I have heard of Brad Larson's GPUImage and so I downloaded it and tried to manipulate it to be more familiar with the code.</p>
  
  <p>Now, I made a new project in Xcode and added it on my frameworks, but i don't have any idea how to use it on a new project.</p>
  
  <p>How can I properly use GPUImage in my new project?</p>
