 This library provides a JUnit TestRule that plants a temporary Timber tree that pipes any logs sent via Timber to the standard System.out. Once a unit test has completed, the Timber tree is removed to avoid logging unintended test cases.
 
+The rule is extremely useful for Android JUnit tests, as the Timber logs do not show without planting a tree.
+
 ## Usage
 Using the library is very straight forward. An example is as follows:
 
 ```java
 public class TestExample {
     @Rule
-    public TimberTestRule mTimberTestRule = TimberTestRule.builder()
+    public TimberTestRule timberTestRule = TimberTestRule.builder()
             .minPriority(Log.ERROR)
             .showThread(true)
             .showTimestamp(false)

+There are also several factory methods which cover many common cases. These are:

+```java
+public class TestExample {

 ### Configuration
 As seen in the example above, there are many ways to modify the output using the following behaviours:
 - The minimum log level to output.
