0 mining threads?

Hi
I have installed the zcash. My config is:

addnode=mainnet.z.cash
rpcuser=username
rpcpassword=`head -c 32 /dev/urandom | base64`
gen=1
genproclimit=$(nproc)

I have generated the t- and z- addresses and started zcash and it says:

You are running 0 mining threads.

You have validated 4121 transactions
You have contributed 0 Sol…
You have completed 0 Equihash…

Is that ok? Do I need to do anything else?

Thank you

Change genproclimit= to your actual number of cores like genproclimit=4

Thanks that has worked.
