Work in progress...
v0.0.0 is not a release but there is lots inside it, and lots more coming!
In the docker/legacy directory, if you are running linux and have docker installed, if you run source init.sh and halp you will get instructions how to get the legacy parallelcoind running in a docker (for windows/mac you will need to control it differently, possibly mac can use the aliases, on windows maybe a mingw shell). Basically, to make it run, you can do a one liner:
.stop;.rm;.build;.run;.start
and it will be listening on 127.0.0.1:11048 for RPC and 0.0.0.0:11047 for p2p communication.
