i've downloaded geth but i don't know if it's doing anything. the terminal says "Fatal: Error starting protocol stack: resource temporarily unavailable" when i try to start it. i'm not really sure what all info is needed to help me, this is all new to me. thanks for any help
First, I would answer your question by saying, No, you have not started geth correctly, the error message is fatal (not sure why without further information). I would recommend downloading Mist wallet, that comes with geth in the back-end and provides a good user interface. https://github.com/ethereum/mist/releases
You haven't mentioned what platform/OS you are on.
