+# 4. Running ORB-SLAM3 with your camera
+
+Directory `Examples` contains several demo programs and calibration files to run ORB-SLAM3 in all sensor configurations with Intel Realsense cameras T265 and D435i. The steps needed to use your own camera are: 
+
+1. Calibrate your camera following `Calibration_Tutorial.pdf` and write your calibration file `your_camera.yaml`
+
+2. Modify one of the provided demos to suit your specific camera model, and build it
+
+3. Connect the camera to your computer using USB3 or the appropriate interface
+
+4. Run ORB-SLAM3. For example, for our D435i camera, we would execute:
+
+```
+./Examples/Stereo-Inertial/stereo_inertial_realsense_D435i Vocabulary/ORBvoc.txt ./Examples/Stereo-Inertial/RealSense_D435i.yaml
