 The `Video` struct stores data about a video file you give it. The code below shows an example of sequentially reading the frames of the given video.
 
+Calling the `Read()` function will fill in the `Video` struct `framebuffer` with the next frame data as 8-bit RGB data, stored in a flattened byte array in row-major order where each pixel is represented by three consecutive bytes representing the R, G and B component of that pixel.

 ## `Camera`
 
 The `Camera` can read from any cameras on the device running Vidio. It takes in the stream index. On most machines the webcam device has index 0. Note that audio retrieval from the microphone is not yet supported.

+## The `SetFrameBuffer(buffer []byte)` method
+
+For the `SetFrameBuffer()` method, the `buffer` parameter must have a length of at least `video.Width() * video.Height() * video.Depth()` bytes to store the incoming video frame. The length of the buffer is not checked. It may be useful to have multiple buffers to keep track of previous video frames without having to copy data around.
+
 ## Images
 
 Vidio provides some convenience functions for reading and writing to images using an array of bytes. Currently, only `png` and `jpeg` formats are supported.
 
 ```go
-// Read png image
 w, h, img, err := vidio.Read("input.png")
-// Error handling...

-// w - width of image
-// h - height of image
