This is my first thread here. Pardon me for any mistake.. ;)
This is a short guide about flashing Extreme Kernel. This article shows you the steps to flash a custom kernel on your Poco F1, replacing the default stock kernel coming with MIUI.
About Extreme Kernel
Extreme Kernel is created by Alex Dev on XDA, based on LineageOS source. It sports some tweaked hardware settings out of the box within the kernel. In short, this kernel will unleash the true potential of your Poco F1 performance by overclocking it safely.

How to Install?
Step 1. You need to unlock the Poco F1 bootloader. This is a must.
Step 2. Flash custom TWRP recovery on your phone (here). You may use the official TWRP of course, but I prefer to use Orange Fox Recovery (here).
Step 3. Download Extreme Kernel for Poco F1 zip file here or here (eXtremeKernel_V9.1_POCOF1_69_HZ.zip). There are two builds that you can choose: 65Hz and 69Hz. Which one? That’s up to you.
You can either download the file directly into your phone or download it to computer first then transfer it to your phone after that.
Step 4. Turn off your phone completely. Once it’s off, press the Power key and Volume Up key simultaneously. This will reboot your phone to custom TWRP recovery.
Step 5. Choose “Install” from the main menu.
Step 6. Locate the Extreme Kernel zip file. Tap on it to select it.
Step 7. Now do the “Swipe to Install” action (Orange fox) or "Swipe to flash" (TWRP).
Step 8. Once done, go back to main menu. Tap “Reboot” then “Recovery“. This will reboot your phone back to recovery again. This is a good practice to make sure the flashed binaries really take place.
Step 9. This time choose “Reboot” then “System“.
Step 10. That’s it. Your phone will now boot into normal mode (e.g: running MIUI).
That's it. Your Poco F1 is now faster than its default state. It is now basically overclocked without having to mess around with individual settings. Flashing a custom kernel may be not as popular as custom ROM. Nevertheless, it allows us to run our favorite ROM (MIUI, LineageOS, PixelExperience, etc) while still controlling the desired performance.
p.s: You can try benchmarking your phone performance using app like Antutu, before and after flashing the kernel.
