How to make "Enable GPU Instancing" checkbox appear on the shader?

I have written a very basic shader as follows. What I have to add to enable GPU instancing?

Code (CSharp):

1. Shader "Unlit/NoteColor"
2. {
3.     Properties
4.     {
5.         _Color ("Main Color", Color) = (1,1,1,1)
6.         _MainTex ("Texture", 2D) = "white"
7.     }
8.     SubShader
9.     {
10.         Tags { "RenderType"="Opaque" }
11.  
12.         Pass
13.         {
14.             ZWrite Off
15.             CGPROGRAM
16.             #pragma vertex vert
17.             #pragma fragment frag
18.             #pragma target 2.0
19.            
20.             #include "UnityCG.cginc"
21.  
22.             struct appdata
23.             {
24.                 float4 vertex : POSITION;
25.                 float2 uv : TEXCOORD0;
26.             };
27.  
28.             struct v2f
29.             {
30.                 float2 uv : TEXCOORD0;
31.                 float4 vertex : SV_POSITION;
32.             };
33.  
34.             sampler2D _MainTex;
35.             float4 _MainTex_ST;
36.             fixed4 _Color;
37.            
38.             v2f vert (appdata v)
39.             {
40.                 v2f o;
41.                 o.vertex = UnityObjectToClipPos(v.vertex);
42.                 o.uv = TRANSFORM_TEX(v.uv, _MainTex);
43.                 return o;
44.             }
45.            
46.             fixed4 frag (v2f i) : SV_Target
47.             {
48.                 fixed4 col = tex2D(_MainTex, i.uv);
49.                 return col;
50.             }
51.             ENDCG
52.         }
53.     }
54. }
55.  

For example, this checkbox is available in Mobile/Diffuse.

 

there is example in docs,

Thanks. I have been there before but how did I miss that...

 

#pragma multi_compile_instancing
