 # The Pipeline
 
 ## What's a pipeline?
-If you're familiar with OpenGL, you may remember using shader programs. You can think of a pipeline as a more robust version of that. A pipeline describes all the actions the gpu will preform when acting on a set of data. In this section, we will be creating a `RenderPipeline` specifically.

 ## Wait shaders?
 Shaders are mini programs that you send to the gpu to perform operations on your data. There are 3 main types of shader: vertex, fragment, and compute. There are others such as geometry shaders, but they're more of an advanced topic. For now we're just going to use vertex, and fragment shaders.
