1: Hash Rate, or approximated hashes you will recieve per second.
2: Accepted Hashes, which determines how many Satoshis you get.
3: Pending Satoshis, the number of satoshis you will get. (Sends to your account once you reach 100 Satoshis.)
4: Total EXP gained, helps you level up.
5: Start/Stop Mining
6: Number of CPUs used to mine. (WARNING!!! DON'T SET THIS ABOVE 4, IT CAN CAUSE DAMAGE TO YOUR COMPUTER!)
7: Break time, how much time it waits until starting mining again after 30 minutes.
8: Referal Link, can be used to increase earnings. (DO NOT POST THIS IN THE CHAT! IT IS AGAINST THE RULES AND YOU WILL BE BANNED BY THE MODERATORS!)
9: Your current boost. This will increase slightly with each level up. As you can see, my level here is 12, so my bonus is 0.77%
To begin mining, press the "Start Mining" button. You should see your hash rate increase/ decrease depending on your settings. After a short period of time, your Accepted Hashes, Satoshis, and EXP should increase. That is all you need to do. You can now open a new tab and do something else, like work, or a game, or whatever you want. (I recommend setting the number of CPUs to 2 if you are planning on multitasking.) Once you reach 100 Satoshis, they will be sent to your FaucetHub account.
