 Creating a Skia "Hello World!"
 ==============================
 
 This tutorial will guide you through the steps to create a Hello World Desktop
 application in Skia.

 ### Run the SkiaExamples.
 
 You should see a window open displaying rotating text and some geometry.
 
 Step 3: Create your own Sample
 ------------------------------
 
 Create a file `experimental/SkiaExamples/Tutorial.cpp` within the Skia tree.  Copy the following code:

 #include "SkExample.h"

 };

 }
 static SkExample::Registry registry(MyFactory);

 Step 4: Compile and run SkiaExamples with your Sample
 -----------------------------------------------------
 
 Here is what you have to do to compile your example. There will be
 functionality to make this easier, but for now, this is what you have to do:
-  * Open `gyp/experimental.gyp` and look for the `SkiaExamples` target.
-  * In the 'sources' section of the SkiaExampels target, add

     `../experimental/SkiaExamples/Tutorial.cpp` to the list of sources.
-  * Repeat Step 2 to update our gyp targets and build our example.
-  * Run the SkiaExamples, specifying the name of our new example: `$> out/Release/SkiaExamples --match Tutorial`

 Step 5: How to iterate through multiple examples

 string matches more than one example, you can use the *n* key to iterate
 through all of the examples registered.
