 BetterBuilder is a [Java annotation processor](https://docs.oracle.com/javase/8/docs/api/javax/annotation/processing/Processor.html) used for
-automatically generating better builder codes([builder design pattern](https://en.wikipedia.org/wiki/Builder_pattern#Java)) with fluent get/set methods, 
+automatically generating **better** builder codes([builder design pattern](https://en.wikipedia.org/wiki/Builder_pattern#Java)), 
 which can make coding much more comfortable.
 
+### Why better ?

++ [configurable get/set](#field-ignore).

 It is for those **fields that aren't allowed to be changed or accessed after 
 initialization**.
 
+### Type-Safe Builder
+
+When we use builder pattern to generate our object, some fields are supposed to be
+initialized. But the classic pattern does not guarantee this.
+
+BetterBuilder provides a type-safe builder pattern. Once the fields annotated with
+@Required haven't been initialized, the goal object will not be generated[instead, an IllegalArgumentException will be thrown].
+
+```java
+@BetterBuilder(BUILDER_TYPE = BuilderType.TYPE_SAFE, fluentSet = false, fluentGet = true)
+public class TypeSafe {
+    @BetterBuilder.Required
+    private Integer ID;
+    @BetterBuilder.Required
+    private String name;
+    private Boolean PID;
+    private Long PID79211;
+}
