+## Adjusting the effect
+
+The look of the CRT can be tuned with several settings:
+
+- **Line width** and **Line contrast** control the visible scanlines. Enable **Show vertical lines** to draw the lines vertically instead of horizontally.
+- **Curvature** bends the image outwards to imitate the bulge of an old screen (`0` keeps it flat).
+- **Noise** and **Noise size** add static grain. **Noise Frequency** sets how many times per second the noise is refreshed (`0` freezes it).
+- **Vignetting**, **Vignetting alpha** and **Vignetting blur** darken the corners of the screen.
+- **Interlaced Lines Speed** animates the scanlines to make them scroll over time.

 You can use this effect to apply all manner of warping effects. Currently, the `r` (red) property of the texture is used to offset the x-axis and the `g` (green) property of the texture is used to offset the y axis.
 
+The **Displacement map texture** is the image used to drive the distortion, and **Scale on X axis** / **Scale on Y axis** set how strongly pixels are shifted along each axis (larger values give a stronger warp).
+
 > It uses the values of the displacement map to look up the correct pixels to output. This means it's not moving the original. Instead, it's starting from the original output and displays the screen differently based on the displacement map. For example, if a displacement map pixel has red = 1 and the filter scale is 20, this filter will output the pixel approximately 20 pixels to the right of the original.

+- **Blur** softens the edges of the shadow, and **Quality** controls how smooth that blur looks (higher values are smoother but slightly more costly).

 This is a faster version of the traditional "Blur" effect. It's recommended that you use this one rather than the "Gaussian" blur effect.
 
+## Adjusting the effect

+- **Blur** sets the overall strength of the blur.
+- **Pixelize X** and **Pixelize Y** let you stretch the blur more on one axis, which is useful for directional (motion-like) blurring.
+- **Quality** controls how smooth the blur looks. Higher values look better but cost more performance.

+Each color channel has its own **X offset** and **Y offset** (for red, green and blue). By shifting the channels in different directions you control the strength and direction of the chromatic aberration. Small offsets give a subtle glitch or damaged-screen look, while large offsets create a strong distorted effect.
