Install (same as Bitcoin Core) and connect to public nodes:
Click 'Help' -> Debug Window -> Console - Paste
addnode "22.214.171.124:6703" "add"
addnode "126.96.36.199:6703" "add"
addnode "188.8.131.52:6703" "add"
It will download until 530,501 blocks, at which point it may need a restart to be on the 6703 port (instead of 8333). From here you should be able to begin mining (after opening port 6703).

we all inhabit this planet.
We all breathe the same air.
We all cherish our children's future.
And we are all mortal."
