+# How to Compile
+
+## Requirements
+- Mac OS X 10.6+ (I use 10.7.3)
+- Xcode 4+
+
+## Instructions
+
+1. **Checkout [openFrameworks](https://github.com/openframeworks/openFrameworks)**
+
+        git clone https://github.com/openframeworks/openFrameworks.git
+
+	Be patient. It may take a while.
+
+2. **Build openFrameworks**
+
+    2.1. Open `openFrameworks/apps/devApps/_DeployExamples/deployExamples.xcodeproj`
+
+    2.2. Build and Run. 
+
+    2.3. Make sure `openFrameworks/libs/openFrameworksCompiled/lib/osx/openFrameworksDebug.a` was generated.
+
+3. **Checkout the [Perfume openFrameworks example](https://github.com/perfume-dev/example-openFrameworks)**
+
+        git clone https://github.com/perfume-dev/example-openFrameworks.git
+
+    You need to put it under `openFrameworks` or change the xcode config file manually. I suggest that you put it under `openFrameworks`. The path should look like this: `openFrameworks/example-openFrameworks/ofxBvh/...`
+
+4. **Download the Perfume bvh and BGM from [Perfume Global Site](http://www.perfume-global.com)**
+
+    In case you couldn't find it, the download section is located at the top left corner.
+
+    Extract files to `openFrameworks/example-openFrameworks/ofxBvh/example-sync-sound/bin/data`. The `data` folder should contains one folder called `bvhfiles` and a wav file `Perfume_globalsite_sound.wav`.
+
+5. **Run the `example-sync-sound`**
+
+	Open `example-sync-sound.xcodeproj` and run. If GLUT.framework wasn't linked correctly, you need to add it manually.
+
+# Have fun!
