-            OpenDataCam consists of a camera attached to a mini computer. It's running an object detection algorithm
-            that counts and tracks moving objects. The board is equipped with a GPU (graphical processing unit), which
-            allows it to process many parallel image threads at once. The perfect tool for image analysis and video

-            On the software side OpenDataCam is running <a href="https://pjreddie.com/darknet/yolo/" target="_blank">YOLO</a> — an object detection library. YOLO is trained to detect
-            objects in images. The attached camera feeds YOLO with a video, YOLO then outputs all objects in each frame.
+            <p>
+              OpenDataCam uses machine learning to detect objects in videos and camera feeds.
+              It then follows the objects as they move accross the scene.
+            </p>
+            <p>
+              Users easily define counters via their browser, and every time an object crosses the
+              counter, OpenDataCam takes count.

-            OpenDataCam is not tied to a specific housing, instead you can design your own or use an already existing casing. We used the <a href="http://naturebytes.org/our-tech/" target="_blank">Wildlife Cam Casing by Naturbytes</a> to protect the hardware in the wild. Have a look at this <a href="https://github.com/opendatacam/opendatacam/blob/master/documentation/jetson/HOUSING.md">tutorial</a> to see how the set up the the Jetson NANO in the Wildlife Cam Casing.
+            <p>
+              The simplest way to get started with OpenDataCam is downloading our <a href="https://hub.docker.com/r/opendatacam/opendatacam">Docker images</a> and run it your computer, server or Jetson device.
+              As long as it has a NVIDIA GPU, it can run OpenDataCam.
