 The filter uses the first 200 IMU messages to initialize the gyro bias, acc bias, and initial orientation. Therefore, the robot is required to start from a stationary state in order to initialize the VIO successfully.
 
-## Example Usage
 
-There are launch files prepared for the EuRoC and fast flight dataset separately. Upon launching the `msckf_vio_*.launch`, two ros nodes are created:
-* `image_processor` takes the stereo images to detect and track features.
-* `vio` takes the feature measurements and tightly fuses them with the IMU messages to estimate pose.
+## EuRoC and UPenn Fast flight dataset example usage
+
+Once the `msckf_vio` is built and sourced (via `source <path to catkin_ws>/devel/setup.bash`), there are two launch files prepared for the [EuRoC](https://projects.asl.ethz.ch/datasets/doku.php?id=kmavvisualinertialdatasets) and [UPenn fast flight](https://github.com/KumarRobotics/msckf_vio/wiki/Dataset) dataset with launch files `msckf_vio_euroc.launch` and `msckf_vio_fla.launch` respectively. The launch files instanciates two ROS nodes:
+
+* `image_processor` processes stereo images to detect and track features
+* `vio` obtains feature measurements from the `image_processor` and tightly fuses them with the IMU messages to estimate pose.
+
+These launch files can be executed via
+
+```
+roslaunch msckf_vio msckf_vio_euroc.launch
+
+or 
+
+roslaunch msckf_vio msckf_vio_fla.launch
+```
+
+Once the nodes are running you need to run the dataset rosbags, for example:
+
+```
+rosbag play V1_01_easy.bag
+```
+
+As mentioned in the previous section **The robot is required to start from a stationary state in order to initialize the VIO successfully**
+
+To visualize the pose and feature estimations you can use the provided rviz configurations found in `msckf_vio/rviz` folder to visualize corresponding datatset estimations (EuRoC: `rviz_euroc_config.rviz`, Fast dataset: `rvis_fla_config.rviz`).
