 #### General
 
-- Added an example that splits up large data across multiple buffers and accesses them as a single contiguous array in the shader, demonstrating the naga/wgsl only `binding_array`, and some of the, less documented `wgpu::Features`.

 # big-compute-buffers
 
 This example assumes you're familiar with the other GP-GPU compute examples in this repository, if you're not you should go look at those first.
 
-Showcases how to split larger datasets (things too big to fit into a single buffer), across multiple buffers whilst treating them as a single, contiguous buffer on the GPU.
+Demonstrates how to split larger datasets (things too big to fit into a single buffer), across multiple buffers whilst treating them as a single, contiguous buffer on the GPU.
 
 - Creates a large set of buffers totalling `1GB`, full of `0.0f32`.
 - Moves those buffers to the DEVICE.

+Note:
+- Large buffers can fail to allocate due to fragmentation issues.
+- Working with large buffers is not always ideal, you should also see the pagination example to see if that approach suits your needs better.
