+## ZeroTier with Scala via JNI
+***
+
+To get this example project to work, do the following:
+
+- From libzt main directory, build shared library: `make shared_jni_lib`
+- Copy the resultant dynamic library (`*.so` or `*.dylib`) from `build/` to this current directory
+- Change to this directory and `make example_scala_app`
+- Run: `scala -cp "." ExampleApp`
+
+
+Notes:
+
+Upon execution, it will load the libzt dynamic library via the `loadLibrary` method and begin generating an identity.
