 # 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.

 2. Because we've created a new bind group, we need to specify which one we're using in the shader. The number is determined by our `render_pipeline_layout`. The `texture_bind_group_layout` is listed first, thus it's `group(0)`, and `uniform_bind_group` is second, so it's `group(1)`.
 3. Multiplication order is important when it comes to matrices. The vector goes on the right, and the matrices gone on the left in order of importance.
