 ## ThrowOnCircularReferences
 
-**TODO**
+**Description:** Whether or not to throw on encountering a circular reference or to terminate it with null.
+**Type:** `boolean`
+**Default:** `false`
 
-## NumericEnums
+### Example 1 - false (default)
+
+When disabled, the offending reference will simply be `null`'d out.
+
+```c#
+public class Circular {
+	public int A { get; set; }
+	public Circular B { get; set; }
+}
+
+var circular = new Circular() { A = 1 };
+circular.B = circular;
 
-**TODO**
+Console.WriteLine(PhpSerialization.Serialize(circular, new (){ ThrowOnCircularReferences = false}));
+// Output: a:2:{s:1:"A";i:1;s:1:"B";N;}
+```
+
+### Example 2 - true
+```c#
+var circular = new Circular() { A = 1 };
+circular.B = circular;
+
+Console.WriteLine(PhpSerialization.Serialize(circular, new (){ ThrowOnCircularReferences = true }));
+// Throws System.ArgumentException with Message: "Input object has a circular reference."
+```
+
+## NumericEnums
 
-## DefaultOptions
+**Description:** Whether to serialize enums as numeric values (integers) or using their string representation via `Enum.ToString()`.
+**Type:** `boolean`
+**Default:** `false`
 
-**TODO**
+### Example 1 - false (default)
+```c#
+public enum MyEnum {
+	A = 1,
+	B,
+}
+Console.WriteLine(PhpSerialization.Serialize(MyEnum.A, new (){ NumericEnums = false }));
+// Output: s:1:"A";
+```
 
+### Example 2 - true
+```c#
+Console.WriteLine(PhpSerialization.Serialize(MyEnum.A, new (){ NumericEnums = true }));
+// Output: i:1;
+```
