+# Working with this Repo
+
+This repository consists of the main parts (API & CLI) and it's own "playground" ASP.NET Core application. Both main parts produce local NuGet packages, that are versioned with 1.0.0. The first thing you will need is to run one of the buildAll scripts (.cmd for Windows, the other for OSX/Linux).
