 ## Usage (JVM)
 
 The main class for encoding and decoding HCERT data is `ehn.techiop.hcert.kotlin.chain.Chain`. For encoding, pass an instance of a `GreenCertificate` (data class conforming to the DCC schema) and get a `ChainResult`. That object will contain all revelant intermediate results as well as the final result (`step5Prefixed`). This final result can be passed to a `DefaultTwoDimCodeService` that will encode it as a 2D QR Code.
