 ORB-SLAM3 is the first real-time SLAM library able to perform **Visual, Visual-Inertial and Multi-Map SLAM** with **monocular, stereo and RGB-D** cameras, using **pin-hole and fisheye** lens models. In all sensor configurations, ORB-SLAM3 is as robust as the best systems available in the literature, and significantly more accurate.

 ### Building the nodes for mono, mono-inertial, stereo, stereo-inertial and RGB-D
 Tested with ROS Melodic and ubuntu 18.04.
 
 1. Add the path including *Examples/ROS/ORB_SLAM3* to the ROS_PACKAGE_PATH environment variable. Open .bashrc file:
-
+  ```
+  gedit ~/.bashrc
+  ```
 and add at the end the following line. Replace PATH by the folder where you cloned ORB_SLAM3:
