+## Introduction
 
 KNoT Thing library is a lightweight C/C++ library built to use minimal CPU
 and memory resources. It is intended to run on KNoT Nodes (Things) (see KNoT

 It provides the Radio and Protocol abstractions for the application. The application

-Compilation and installation
-============================
+## Compilation and installation
 
 Currently the KNoT Thing library supports only the Arduino platform. The build process will generate an Arduino library zip file (KNoTThing.zip) containing all source code. This zip file can be imported on Arduino IDE.
 
 In order to compiler the source code you need following software packages:
-	- GCC compiler
-	- GNU C library
+- GCC compiler
+- GNU C library
 
 How to build:
-	make
