+## Creating JavaCard STK Applets
+
+Use the hello-stk example to get started.
+
+	$ mkdir javacard
+	$ cd javacard
+	$ git clone https://github.com/Shadytel/sim-tools.git
+	$ git clone https://github.com/Shadytel/hello-stk.git
+	$ cd hello-stk
+	$ make
+	
+To install the applet onto a SIM card, first set the type of reader you are using.
+
+	# For PCSC readers:
+    $ export SHADYSIM_OPTIONS="--pcsc"
+
+	# For USB-serial readers:
+    $ export SHADYSIM_OPTIONS="--serialport /dev/ttyUSB0"
+
+    $ make install
+    
+The shadysim tool has lots of other options.
+
+    $ ./sim-tools/bin/shadysim --help
