+### Adding the ScrollableGraphView to your project:
 
-1. Add [GraphView.swift](graphview_example/GraphView/GraphView.swift) to your project in Xcode  
+Add the ```ScrollableGraphView``` class to your project. There are two ways to add the ScrollableGraphView to your project.
 
-2. Create a GraphView instance and set the data and labels  
+#### Manually
+Add [ScrollableGraphView.swift](graphview_example/ScrollableGraphView/ScrollableGraphView.swift) to your project in Xcode  
+
+#### CocoaPods
+Add ```pod 'ScrollableGraphView'``` to your Podfile and then make sure to ```import ScrollableGraphView``` in your code.
+
+### Creating a graph and setting the data.
+
+1. Create a ScrollableGraphView instance and set the data and labels  
     ```swift
-    let graphView = GraphView(frame: someFrame)
+    let graphView = ScrollableGraphView(frame: someFrame)
     let data = [4, 8, 15, 16, 23, 42]
     let labels = ["one", "two", "three", "four", "five", "six"]
