+== How to develop ==
+
+To write BTstack-based applications, you don't need to compile the BTstack Cydia package. You can just install it on your 
+JB iOS device and copy /usr/lib/libBTstack.dylib into your project and add btstack/include to your project includes. 
+See btstack/platforms/example/WiiMoteOpenGLDemo for a Xcode-base example. In general, I highly recommend to use theos
+to create apps & daemons for JB iOS devices instead of using Xcode.
+
+== Compile Instructions ==
+
+Install the following tools:
+- Xcode 6.4 as /Applications/Xcode.app
+- Xcode 4.4.1 as /Applications/Xcode-4.4.1.app/
+- rpetrich's theos fork with "lippoplastic" support from https://github.com/rpetrich/theos
+
+Set the $THEOS environment variable to the location of theos, e.g. like:
+
+	export THEOS=/Projects/theos
+
+Go to btstack/platforms/ios and run make
+
+	cd btstack
+	make package
+
+If everything went right, you'll end up with a .deb package that you can install via:
+
+	make install
+
