 Exporting your project
----------------------
+----------------------
 
-In the Godot editor, open the Export window from the Project menu. When the 
-Export window opens, click Add.. and select iOS. 
+In the Godot editor, open the **Export** window from the **Project** menu. When the 
+Export window opens, click **Add..** and select **iOS**. 
 
-If you haven't downloaded the Godot export templates for your version, a 
-"Manage Export Templates" link will appear on the bottom of the window. Click
-that link and install the templates, it may take several minutes. 
+The following export options are required. Leaving any blank with cause the

-Make sure to specify the File field. It will be used as your Xcode project name. 
+When the export completes, the options I used will create a directory that looks like this:

+
+I can now open **exported_xcode_project_name.xcodeproj** to build and deploy my game
+like any other iOS app.

+
+Active development considerations
+---------------------------------
+
+The above method creates an exported project that you can build for release, but you
+have to re-export every time you make a change in Godot. 
+
+While developing your game, you can speed this process up by building your Godot project
+files directly into your app. 
+
+In the following example:
+
+  * **exported_xcode_project_name** is the name of the exported iOS application (as above). 
+  * **godot_project_to_export** is the name of the Godot project I exported it from. 
+
+Steps to use your Godot project directory in Xcode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Start from an exported iOS project like I created above.
+2. In Finder, drag your Godot project folder into the Xcode file browser. 
+
+.. image:: img/ios_export_add_dir.png
+
+3. In the dialog, make sure **Create folder references** is selected. This means
+that you can continue to edit your Godot project in its current location.
+
+.. image:: img/ios_export_file_ref.png
+
+4. You now see the **godot_project_to_export** directory in the Xcode file browser. 
+5. Delete **exported_xcode_project_name.pck** from the Xcode project.
+
+.. image:: img/ios_export_delete_pck.png
+
+6. Open **exported_xcode_project_name-Info.plist** and add a string property named
+**godot_path** (this is the real key name) with a value **godot_project_to_export** 
+(this is the name of your project)
+
+.. image:: img/ios_export_set_path.png
+
+That's it! Continue to edit your project in the Godot editor and build it in Xcode when you 
+want to run it on a device. 
 
-Go to the export directory you specified, open the .xcodeproj file and build and 
-run as normal.
