 OSL shaders
 
+### General Shader Installation
+- You can copy `.osl` and `.ui` files to your OSL directory. For example, `C:\Program Files\Autodesk\3ds Max 2022\Plugins\OSL`.
+- You may also copy this whole directory in that folder, which will add the shader in a sub-menu.
+- You should see the shader in your material editor drop-down on next Max launch.

 SimpleOcean is a Gerstner Wave implementation to simulate ocean vector displacement. It isn't highly complex, but should do the job when you need a quick & dirty ocean. The shader outputs a main vector displacement map and multiple utility maps, like foam maps, above sea map, etc.
 
-Connect the main output to Arnold Properties Vector Displacement map input.
+### Getting Started
+- Connect the main output to **Arnold Properties Vector Displacement** map input.
+  - This is important, as the shader outputs vector displacement which isn't compatible with other displace inputs (like Physical Material, Displace modifier, etc).
+- Use Active Shade to see the results.
 
 ### Known Issues
-- **Animation doesn't work!** There is currently a bug with the Arnold Properties Displacement map input. Once that is fixed I can test animation.
+- **Animation doesn't work!**
+  - There is currently a bug with the Arnold Properties Displacement map input. Once that is fixed I can test animation.
 - When using very large maps, the ocean generation can be slow.
+- Some of the hashing options aren't ideal and produce banding.
 
-### Getting Started
-The following should create a decently shaded ocean. For best results use and HDRI environment.
+### Material Settings
+The following should create a decently shaded ocean. For best results use and HDRI environment. You can place a large dark plane underneath the ocean, which improves realism a little bit. A more in-depth video is coming to discuss node details.
