+
+## 1. Getting started with Blinky
+
+Blinky example for Mbed OS
+
+### 1-1. Import the example code
+
+From the command-line, import the example:
+
+```
+mbed import https://github.com/SigmaDeltaTechnologiesInc/SDT-example-blinky
+cd SDT-example-blinky
+```
+
+### 1-2. Compile
+
+Invoke `mbed compile`, and specify the name of your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`) and your platform. 
+For example, for the GCC_ARM and SDT64B:
+
+```
+mbed compile -t GCC_ARM -m SDT64B
+```
+
+Your PC may take a few minutes to compile your code. 
+At the end, you see the following result:
+
+```
