+##Setup
+
+1. [Clone][clone_link] or [download][download_link] the STK into your project's directory.
+
+1. Open the **STK for iOS** folder, and drag and drop **STK.xcodeproj** into your Xcode project.
+
+1. Open your project's settings, open the *Build Phases* tab. In the *Link Binary with Libraries* section, add **libSTK.a**. 
+![][linking_libSTK_screenshot]
+
+1. In your project's settings, open the *Build Settings* tab. In the *Search Paths* section, double click on the field to the right of *Header Search Paths*, and add the path to the STK's **include** directory relative to your Xcode project's directory.
+![][header_search_paths_screenshot]
+
+
+##Usage
+
+1. Import the STK classes in the source files you require. 
+  * E.g. `#import "SineWave.h"`
+
+1. Change the extension of Objective-C files that import STK files to **.mm**. 
+  * E.g. **ViewController.m** —> **ViewController.mm**
+
+You can also look at the [iOS Demo project](..projects/demo/iOS%20Demo) for a sample usage. 
+
+
+##Troubleshooting
+
+###'FileName.h' file not found
+
+If you get this error when `#import`ing an STK header, you have added the wrong header search path for the STK in your project's settings (see Step 4 in Setup)
+
+The STK's header search path you need to add is the path to the STK's **include** directory relative to your project's directory (as if you were `cd`ing into it). For example, it is `stk/include/` if the stk directory is inside your project's directory, but it is `../stk/include/` if both share the same directory. 
+
+If this problem doesn't go away:
+
+1. Delete **STK.xcodeproj** from your Xcode project
+1. Move the STK directory within your project's directory. 
+1. Follow step 1 from **Setup**, add `stk/include` to the *Header Search Paths*.
+
+###Raw waves
+
+If you use a class that makes use of raw waves (such as `Mandolin`, `Wurley`, or `Rhodey`) you need to copy the STK's raw wave files into your bundle. You'll know you need to if you get this runtime error: 
+`FileRead::open: could not open or find file (../../rawwaves/filename.raw)!`
+
+1. Open your project's settings, open the *Build Phases* tab. 
+1. In the *Copy Bundle Resources*, drag and drop **rawwaves.bundle** (it's located in **STK.xcodeproj**'s **Helpers** folder). 
+1. Then add this code before using a class that needs the raw waves: 
+
+```objective-c
+NSBundle *rawwaveBundle = [NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"rawwaves" withExtension:@"bundle"]];
+stk::Stk::setRawwavePath([[rawwaveBundle resourcePath] UTF8String]);
+```
+
+
+###rawwaves.bundle: No such file or directory
+
+This means that **rawwaves.bundle** hasn't been copied to the build folder, so you'll need to do it manually:
+
+Select the rawwaves scheme:
+
+![][rawwaves_scheme_screenshot]
+  
+Build it (⌘+B)  then build your project's main scheme. 
+
+###Apple Mach-O Linker Error
+
+This means that **STKLib.a** isn't being linked to your binary. Follow step 2 above in Setup.
