+  This example provides shows how to use blending in WebGPU. It draws a texture with diagonal lines
+  on top of a canvas with a CSS based checkerboard background. It then draws a texture with
+  3 blurry circles on top the first texture with [blending settings](https://gpuweb.github.io/gpuweb/#color-target-state).
+  This lets you see both the effect of blending settings in WebGPU and the final result when composited on top of the canvas.
+  See [this article](https://webgpufundamentals.org/webgpu/lessons/webgpu-transparency.html)
+  for a more detailed explanation.
