Before ClashPilot
ClashPilot plays the game inside an emulator on your Windows PC. Before the bot can do anything, the emulator and the game have to be there.
Install MuMu Player
Download MuMu Player from its own website and install it. ClashPilot works with MuMu Player today; others may follow.
Make one instance
Open MuMu Player and make one instance. That is the instance ClashPilot plays, and you point the bot at it later, on its Settings page.
Install Clash of Clans in it
Inside the instance, install Clash of Clans and sign in the way you would on a phone. ClashPilot never asks for your Supercell ID or password: you sign in yourself, inside the emulator, and the bot never sees them.
Play past the tutorial
Play the game yourself until the tutorial is over and you have a normal village. The bot is made for a village, not for the tutorial.
Use an account you can afford to lose
Automation is against Supercell's terms of service, and an account running a bot can be banned. ClashPilot takes breaks and never taps the same way twice, which lowers the risk; it does not remove it. Use an account you can afford to lose.
