+# Overview
+
+[MegaDetector](https://github.com/agentmorris/MegaDetector/) is an AI model that identifies animals, people, and vehicles in camera trap images (which also makes it useful for eliminating blank images).  This model is trained on several million images from a variety of ecosystems.
+
+# Getting started
+
+If you are a biologist looking to get started with MegaDetector, you probably don't want to download the model directly; instead, check out [AddaxAI](https://addaxdatascience.com/addaxai/) (formerly EcoAssist), a GUI-based tool for running AI models on camera trap images.
+
+If you want to run MegaDetector directly, check out the [MegaDetector User Guide](https://github.com/agentmorris/MegaDetector/blob/main/megadetector.md).
+
+# Variations
+
+Two variations of the model are included: MDv5a and MDv5b.  
+
+MegaDetector v5b was trained only on camera trap images (several million images).
+
+MegaDetector v5a is trained on the same camera trap data as MegaDetector v5b, but it is also trained on images from the [COCO dataset](https://cocodataset.org/#home). 
+
+Both variations use the same architecture (YOLOv5x6).
+
+# License information
+
+Both variations were trained with a [GPL-licensed version of the YOLOv5 framework](https://github.com/ecologize/yolov5).  No restrictions are placed on the use of the model by the MegaDetector developers; the applicable license may be determined by the code you use to run the model.
