 Explanation of the library usage
 --------------------------------
-###RTabMap
+### RTabMap
 RTab Map is a Simultaneous Localization and Mapping (SLAM) library making use of RGB-D sensors. 
 It can utilize different kinds of sensor (kinects, zed camera etc).
 It is used to compute the relative movement of the platform. 
 In current implementation only the speed (3 linear and 3 angular components) are utilized.
 
-###Kalman Filter
+### Kalman Filter
 Extended Kalman filter is used to filter and smooth the speed estimation of the platform provided by RTab Map library. 
 The position and speed provided by RTabMap is quite noisy and the position itself can vary in successive steps for more than 5 cm. 
 The speed is therefore filtered by Extended Kalman filter. 
 The robot_localization ros package needs the configuration file which is located at ....

+### Freenect
 Freenect is open source library to get data from the Microsoft Kinnect sensor.
