 # GetSet
 GetSet is a JavaScript Micro-library for getting and setting things in HTML Elements. Basically, the idea behind this library is to allow the developer to perform a Get and Set operation in one go.

-<pre>
-	<code>
-		OnYourMarks.GetSet("main-page-heading", "New Heading").Go();
-	</code>
-</pre>
+Use-case #1:
+
+```js
+OnYourMarks.GetSet("main-page-heading", "New Heading").Go();
+```
+
+Use-case #2:
+
+```js
+if(OnYourMarks.GetSet("main-page-heading", "New Heading").Go() >= 0)
+{
+	// Success: Do something.
+}
+else
+{
+	// Failure: Do something else.
+}
+```
+The `Go` function returns `0` if the operation was successful, otherwise, it returns `-1`.
