The release (not source) zip file contains the alpha1 release and a simple, pre-configured „Braitenberg“ type agent.
After extracting the archive, call ./run.sh and point your browser to http://localhost:6543 - log in as „admin“, no password required.
Please note that this is alpha software. It contains experimental code, we might and probably will change APIs in the future, and performance has not been a concern at all so far.
