 # ECS1300: Use Proper Initialization for Static Class Members
 
+This rule is described in detail in [Effective C#: 50 Specific Ways to Improve your C#](https://www.oreilly.com/library/view/effective-c-50/9780134579290/).
+
 ## Cause
 
 Static fields initialized with complex expressions or method calls that might throw exceptions can cause runtime errors during type initialization. These exceptions occur before any static constructors or error-handling mechanisms can intercept them, potentially crashing the application.
