 		When the {@code VK_AMD_shader_trinary_minmax} device extension is enabled the application $can pass a SPIR-V module to #CreateShaderModule() that uses
 		the {@code SPV_AMD_shader_trinary_minmax} SPIR-V extension.
 
-		This extension introduces 3-parameter {@code min}, {@code max} and {@code med} functions which map directly to the corresponding GCN opcodes:
-		{@code min3}, {@code max3}, {@code med3}
+		This extension is written to provide the functionality of the {@code AMD_shader_trinary_minmax}, OpenGL Shading Language Specification extension, for
+		SPIR-V.
+
+		This extension introduces nine new trinary extended instructions to SPIR-V. These functions allow the minimum, maximum or median of three inputs to be
+		found with a single function call. These operations may be useful for sorting and filtering operations, for example. By explicitly performing a trinary
+		operation with a single built-in function, shader compilers and optimizers may be able to generate better instruction sequences to perform sorting and
+		to other multi-input functions.
+
+		This extension adds the following extended instructions:
+		${ul(
+			"FMin3AMD",
+			"UMin3AMD",
+			"SMin3AMD",
+			"FMax3AMD",
+			"UMax3AMD",
+			"SMax3AMD",
+			"FMid3AMD",
+			"UMid3AMD",
+			"SMid3AMD"
