 This is a shell script that will re-organize the wolfSSL library to be

+the library. This script moves all src/ files to the `IDE/ARDUINO/wolfSSL`
+directory and creates a stub header file called `wolfssl.h`.
 
 Step 1: To configure wolfSSL with Arduino, enter the following from within the
 wolfssl/IDE/ARDUINO directory:
 
-        ./wolfssl-arduino.sh
+        `./wolfssl-arduino.sh`
 
 
-Step 2: Edit <wolfssl-root>/wolfssl/wolfcrypt/settings.h uncomment the define for
-WOLFSSL_ARDUINO
+Step 2: Edit `<wolfssl-root>/IDE/ARDUINO/wolfSSL/wolfssl/wolfcrypt/settings.h` uncomment the define for `WOLFSSL_ARDUINO`
+If building for Intel Galileo platform also uncomment the define for `INTEL_GALILEO`.

 #####Including wolfSSL in Arduino Libraries (for Arduino version 1.6.6)
-1. Copy the wolfSSL directory into Arduino/libraries (or wherever Arduino searches for libraries).
-2. In the Arduino IDE:
-    - Go to ```Sketch > Include Libraries > Manage Libraries```. This refreshes your changes to the libraries.
-    - Next go to ```Sketch > Include Libraries > wolfSSL```. This includes wolfSSL in your sketch.
+
+1. In the Arduino IDE:
+    - In `Sketch -> Include Library -> Add .ZIP Library...` and choose the
+        `IDE/ARDUNIO/wolfSSL` folder.
+    - In `Sketch -> Include Library` choose wolfSSL.
+
+An example wolfSSL client INO sketch exists here: `sketches/wolfssl_client/wolfssl_client.ino`
