Sorry to bother but I got a message when using this json file:
Fatal: Failed to write genesis block: unsupported fork ordering: eip150Block not enabled, but eip155Block enabled at 0
Could you please update this gist?

Simply remove these 3 lines
Line 4,5,6

"homesteadBlock": 0,
"eip155Block": 0, 

"eip158Block": 0

Does anyone know where I can find the docs for the definitions of each property. Is there a genesis.json API doc?

just search them on internet and you are good to go.
