 Installing the HelpStack library is fairly straight-forward.

 #### Step 1 - Configure HelpStack with the Gear of your choice:
 
 Create a custom *Application* class which extends the **Application** class. Be sure to mention it in your manifest as well.
-
-    <application
-      android:name="HSApplication"
-      ...
-    />    
-    
+```xml
+<application
+  android:name="HSApplication"
+  ...
+/>

 Obtain the necessary credentials for the gear of your choice and create a suitable Gear object. Set the Gear object with *HSHelpStack* instance only once. 
 
 ##### Setting the Gear
 
 The general structure of setting a gear is given below: 
-
-    public class HSApplication extends Application {
-      HSHelpStack helpStack;
-
-      @Override
-      public void onCreate() {
-        super.onCreate();
-
-        helpStack = HSHelpStack.getInstance(this); // Get the HSHelpStack instance
-
-        <GearType> <gear> = new <GearType>(<Gear credentials as parameters>); // Create the Gear object 
-
-        helpStack.setGear(<gear>); // Set the Gear
-      }
-    }
+```java
+public class HSApplication extends Application {
+  HSHelpStack helpStack;
+
+  @Override
+  public void onCreate() {
+    super.onCreate();
+
+    helpStack = HSHelpStack.getInstance(this); // Get the HSHelpStack instance
