+# USP0020 The Unity runtime invokes Unity messages
+
+Unity messages should not be flagged as unused because Unity invokes those messages.
+
+## Suppressed Diagnostic ID
+
+IDE0052 - Private method can be removed as it is never invoked.
+
+## Examples of code that produces a suppressed diagnostic
+```csharp
+using UnityEngine;
+
+class Camera : MonoBehaviour
+{
+	void Start()
+	{
+		//Some code
+	}
+
+	/// <summary>
+	/// This reference triggers IDE0052 <see cref=""Start"" />
+	/// </summary>
+	public float speed = 0f;
+}
+```
+
+## Why is the diagnostic reported?
+
+The IDE cannot find any references to the method `Start` and believes it to be unused.
+
+## Why do we suppress this diagnostic?
+
+Even though the IDE cannot find any references to `Start`, it will be called by Unity, and should not be removed.
