+Valid on frames: **Edge** and **Vertex**
+
+Allowed prefixes when operation is AUTO: `get`, `is`, `can`, `set`, `remove`
+
+Annotation arguments:
+
+`value` - The name of the property
+
+`operation` - The operation the method will perform. Must be one of the following: `GET`, `SET`, `REMOVE`, `AUTO`. Defaults to `AUTO`.
+
+The following would bind the method it is used on to the property named `foo`:
+
+```java
+@Property("foo")
+//Method declared here
+```
+
+## GET Operation
+
+Valid method signatures: `( )`
+
+### Signature: `( )`
+
+Valid return types: `Object` or any primitive.
+
+Get the property value of an element. Used when property is not a boolean value.
+
+example:
+
+```java
+@Property("Foo")
+Bar getFoobar();
+```
+
+```java
+@Property("Foo")
+<E extends Bar> E getFoobar();
+```
+
+```java
+@Property("Foo")
+<E> E getFoobar();
+```
+
+```java
+@Property(value = "Foo", operation = Property.Operation.GET)
+Bar obtainFoobar();
+```
+
+## GET Operation (is prefix)
+
+Valid method signatures: `( )`
+
+### Signature: `( )`
+
+Valid return types: `boolean`
+
+Get the property value of an element. Used when property is a boolean value.
+
+example:
+
+```java
+@Property("Foobared")
+boolean isFoobared();
+```
+
+```java
+@Property(value = "Foo", operation = Property.Operation.GET)
+boolean obtainFoobared();
+```
+
+## SET Operation
+
+Valid method signatures: `(Object)`
+
+### Signature: `(Object)`
+
+Valid return types: `void`
+
+Set the property value of an element. The argument can be any class accepted by the underlying graph.
+
+example:
+
+```java
+@Property("Foo")
+void setFoobar(Bar foobar);
+```
+
+```java
+@Property("Foo")
+<E extends Bar> void setFoobar(E foobar);
+```
+
+```java
+@Property("Foo")
+<E extends VectorFrame> void setFoobar(E foobar);
+```
+
+```java
+@Property("Foo")
+void setFoobar(Bar foobar);
+```
+
+```java
+@Property(value = "Foo", operation = Property.Operation.SET)
+void applyFoobar(Bar foobar);
+```
+
+## REMOVE Operation
+
+Valid method signatures: `( )`
+
+### Signature: `( )`
+
+Valid return types: `void`
+
+Remove the property of an element.
+
+example:
+
+```java
+@Property("Foo")
+void removeFoobar();
+```
+
+```java
+@Property(value = "Foo", operation = Property.Operation.REMOVE)
+void removeFoobar();
+```
