+# JavaCard Hardware Wallet
+
+Currently just a skeleton for the hardware wallet.
+
+The .gpshell files are meant to be fed to GPShell. The statuswallet_install.gpshell file is actually dependent on the
+target hw. Currently it assumes that the default VISA AID and keys for the ISD are used, but the version number is 2.
+
+Other files will come and go until they are formalized as test scripts when we have a meaningful specification
+and implementation.
+
+The project is built using Gradle with the [Fidesmo Javacard Gradle plugin](https://github.com/fidesmo/gradle-javacard).
