+# MISP Decaying Models
 
-Test model for DEV and experimentation.
+Starting from MISP 2.4.114, a decaying feature is available to apply decaying on attributes in your MISP instance. MISP comes with a set of default decaying models which
+can be customised by the users. This repository contains all the default models.
+
+## Models
+
+- [nids-simple-model](./models/nids-simple-model.json) - Simple decaying model for Network Intrusion Detection System (NIDS).
+- [phishing-model](./models/phishing-model.json) - Simple model to rapidly decay phishing website.
+
+## How to contribute your decaying model?
+
+It's very easy. Fork the repository, create a new JSON file with your model and make a pull-request.
+
+## License
+
+The MISP decaying models are [dual-licensed](./LICENSE.md) under CC-0 and a simple 2-clause BSD license.
