+# ktor-kodein-exposed
+This project is a sample service using [ktor](https://ktor.io/) (with Netty) and 
+[Exposed](https://github.com/JetBrains/Exposed) ORM. [Kodein](https://kodein.org/di/) is leveraged for  
+dependency injection. The ultimate goal is to incorporate a similar sample service into 
+[cautious-engine](https://github.com/vitdebacco/cautious-engine) to test the performance of various frameworks.
+
+This project was initialized with IntelliJ's Ktor plugin.
