 3. to use [bridge](https://github.com/trezor/trezord-go) with the emulator support, start it with `trezord -e 21324`
 
 Now you can use the emulator the same way as you use the device, for example you can visit our Wallet (https://wallet.trezor.io), use our Python CLI tool (`trezorctl`) etc. Simply click to emulate screen touches.
