Step-by-step:

1. Turn off the phone (press the power button for 10 seconds if it freezes).
2. Press the Power button + Volume up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons and you will see the Recovery menu (black screen with yellow text in English).
