+
+- FXAA
+
+	FXAA is a fast screen space antialiasing method. It detects edges and blurs them.
+
+	Step 1:
+
+	Detect which pixels to apply antialiasing on.
+
+	![](img/fxaa_debug_passthrough.PNG)
+
+	Step 2:
+
+	Determine if the edge is oriented horizontal or vertical. Blue is vertical, yellow is horizontal.
+
+	![](img/fxaa_debug_horzvert.PNG)
+
+	Step 3:
+
+	Determine highest contrast pixel pair orthogonal to the edge. A pair consists of a blue and green pixel in the debug image.
+
+	![](img/fxaa_debug_pair.PNG)
+
+	Step 4:
+
+	Determine the length of the edge by traversing along the orientation of the edge.
 
-### (TODO: Your README)
+	Step 5:
 
-*DO NOT* leave the README to the last minute! It is a crucial part of the
-project, and we will not be able to grade you without a good README.
+	Offset the pixel by its distance to the end of the edge. The closer it is to the edge, the more it is blurred.
