If this is your first time, don't go to a guide yet. Keep reading this article to understand if you're doing the right thing, and be assured.
It assumes you're on stock MIUI with a locked Bootloader. If you're not sure if you're, the guides will show you how to know.
If you want to install a custom ROM, or Root your phone, the first thing to do is unlocking the Bootloader.
Warning: All device data will be erased at the Bootloader Unlocking final step. Don't worry, this guide will tell you when it's time for a backup. Just keep that in mind.
Short: Xiaomi locks the Bootloader. You need to ask for permission using a Mi account and a SIM card, and wait 7 days to unlock the phone. Check How to Unlock the Bootloader.
The Bootloader is the first thing to run when the phone turns on, before Android. The Bootloader is locked for security. If the phone is lost or stolen, a locked Bootloader ensures only Android can modify system files, so it can protect apps and user data from leaking. The phone could still be factory reset and used by whoever has it, but without the password, user data stays safe, and the only possible thing is wipe everything.
After unlocking the Bootloader, system files can be modified by the user, and the Android is considered unprotected because of that. But if the device is encripted, so Android asks for a password to unlock the phone, all user data will still be safe, even with an unlocked Bootloader. To protect user privacy, Android resets to factory settings, and all user data is wiped every time the Bootloader is locked or unlocked. Don't worry, it has to be done only once.
Being able to modify system files is a powerful thing. It can be used to swap the entire Android for some version made by the community, with new features and security updates not included in the stock version. Check Installing a Custom ROM.
It can also be used to Root the system, and the give admin permissions for apps, so they can change system files and perform actions normaly blocked by Android. Be careful, because with great power comes great responsibility. Only give Root permissions to apps you do trust. Check Rooting Android.
