# Generating a custom Shader Graph node
## Step 1: Generate an HLSL function definition
- The function must be preceded by the preprocessor define `UNITY_EXPORT_REFLECTION`
## Step 2: Decorate with Shader Graph hint tags
- See `resources/all_hints.hlsl` for all valid hint tags and usage patterns
- C#-style documentation tags are supported outside of `funchints` or `paramhints` blocks
- Required function hints:
- `sg:ProviderKey`
- `sg:SearchCategory`
- `sg:SearchTerms`
- `sg:DisplayName`
## Step 3: Write the code to an asset
- Search the project for a `ShaderInclude` asset (`.hlsl`) that already contains custom Shader Graph nodes
- If a matching asset exists, show the user its current contents and ask for confirmation before appending the new code
- If no matching asset exists, create a new `.hlsl` asset
- Ensure the file begins with `#include "ShaderApiReflectionSupport.hlsl"`
