 Shaders are loaded from the `--shader` flag in slop. They are delimited by commas, and rendered in order from left to right. This way you can combine multiple shaders for interesting effects! For example, `slop -rblur1,wiggle` would load `~/.config/slop/blur1{.frag,.vert}` and `~/.config/slop/wiggle{.frag,.vert}`. Then render the selection rectangle twice, each time accumulating the changes from the different shaders.
 
-Enough chatting about it though, here's some example shaders you can from [shaderexamples](https://github.com/naelstrof/slop/tree/master/shaderexamples) to `~/.config/slop` to try out!

+The files listed to the right of the `|` are the required files for the command to the left to work correctly.
 * `slop -rblur1,blur2 -b100` | `~/.config/slop/{blur1,blur2}{.frag,.vert}`
