+### Luma Sharpen
+
+Boosts small details. Doesn't cause noticeable halos like a typical sharpening
+filter.
+
+### Color Grading Suite
+
+Control over RGB gamma/intensity, along with a "tint" filter that, with a
+negative intensity, can also be used as a color booster (dunno how this even
+works, I wrote it 7 years ago lol). On top of all that, you can also do the
+same for saturation and value (not hue because that would just be dumb).
+
+### Color Matrix
+
+General purpose color mixing. The matrix is normalized in post. For experienced
+users.
+
+### Hue-Saturation
+
+The GIMP filter in shader form. Allows shifting the hue and tweaking the
+saturation and value of red, yellow, green, cyan, blue and magenta ranges.
+
+### BlurSharpShift
+
+Blurring followed by sharpening, followed by chromatic aberration. This is a
+meme filter chain that a lot of people love for some reason, claiming it adds
+"photorealism" or something.
+
+### Grain
+
+Makes the screen fuzzy. A couple parameters can be tweaked freely.
+
+### Screen Dirt
+
+Overlays a noisy pattern onto the screen to make it filthy. Not a very good
+filter, tbh, but I just kept it in for historical reasons.
+
+### Vignette
+
+Darkens the edges of the screen. Comes with "border blur", which also blurs
+said edges.
+
+### Palette Reduction w/ Dither
+
+Part of the "Retro FX" megashader from old MariENB versions. Does what it says
+on the tin. There's a multitude of palettes available to choose from. Most
+IWADs are covered, along with some notable megawads, various DOS games, and a
+couple "standard" palettes.
