While Apian is in its current very early state of development it turns out that the most convenient way to use it is to check out the source code and build it along with any app you are working on. The example apps ( Beam.Cli, Beam.Unity ) currently expect their repositories to be in the same folder as the other Apian repositories.
To make this a little easier, there are 2 scripts in the same folder as this README file that can automate this for you:
clone-apian-repos.bat(for Windows)clone-apian-repos.sh(Linux/MacOs)
Both of these scripts will first verify that you have the Git Large File Storage extension installed and will then proceed to clone the Apian repositories.
Eventually these repositories will be published as .NET packages and application projects will be able to reference them using PackageReference statements. For now, though, they will have to use ProjectReference statements pointing to the source code.
