 # SabreTools.Models
 
+[![Build and Test](https://github.com/SabreTools/SabreTools.Models/actions/workflows/build_and_test.yml/badge.svg?branch=main)](https://github.com/SabreTools/SabreTools.Models/actions/workflows/build_and_test.yml)
+
 This library comprises of models that represent either directly serializable or representative structures for all SabreTools projects. All of the main models representing metadata files should have parsers created outside of the current code.
 
 Find the link to the Nuget package [here](https://www.nuget.org/packages/SabreTools.Models).
 
+## Releases
+
+For the most recent stable build, download the latest release here: [Releases Page](https://github.com/SabreTools/SabreTools.Models/releases)
+
+For the latest WIP build here: [Rolling Release](https://github.com/SabreTools/SabreTools.Models/releases/rolling)

 ## Missing Metadata Models
 
 The following metadata file formats do not have models included in this library yet and, as such, do not have serializers:
