For solo mining on Windows download the CLI wallet in the announcement post on page 1 and run jimcoind.exe (your wallet must be closed to run the CLI daemon but copy your receiving address first) and once the daemon is synced with the network issue the command,
start_mining YourReceiveAddress NumberOfCPUThreadsToUse
It should display that the miner has started on each thread and if you want to see your hashrate use
show_hr
On linux the commands are the same except for starting the daemon which is done with the command ./jimcoind from within the directory that jimcoind is in.
