+### Pre-installation:
+
+* You must be on the stock ROM on Android 14 or 15 to proceed; you can use XperiFirm to install these versions
+* Optional gapps (from download page, gapps button)
+
+
+### First time installation (clean flash):
+
+* Step 1
+Unlock the bootloader by following the steps at [Sony's website for bootloader unlocking](https://developerworld.wpp.developer.sony.com/open-source/aosp-on-xperia-open-devices/get-started/unlock-bootloader/how-to-unlock-bootloader)
+* Step 2
+Download boot.img, dtbo.img, vbmeta.img, recovery.img, and vendor_boot.img from the download website.
+* Step 3
+Power off the device and boot into bootloader mode by holding Volume Up and connecting the USB cable. There should be a blue asterik in the top left corner of the screen.
+* Step 4
+Connect the phone to your computer and run the following commands from the directory you downloaded the files in:
+```
+fastboot flash boot boot.img
+fastboot flash dtbo dtbo.img
+fastboot flash vbmeta vbmeta.img
+fastboot flash vendor_boot vendor_boot.img
+fastboot flash recovery recovery.img
+```
+* Step 5
+Reboot into recovery by running 
+```
+fastboot reboot recovery
+```
+If the crDroid recovery does not show up, reflash recovery and try again.
+
+* Step 6
+To prevent issues due to the inactive A/B slot being unpopulated or containing much older firmware, we will copy the contents of the active slot to the inactive slot.
+1. Download the copy-partitions-20220613-signed.zip file from [here](https://mirrorbits.lineageos.org/tools/copy-partitions-20220613-signed.zip) 
+2. On the device, select "Apply update", then "Apply from ADB" to begin sideloading.
+3. On the computer, sideload the package by running:
+```
+adb -d sideload copy-partitions-20220613-signed.zip
+```
+Then, on the phone, tap Advanced -> Reboot to recovery.
+
+* Step 7
+1. Download the crDroid Android zip file from [here](https://crdroid.net/pdx237/12)
+2. On the phone, select Factory reset -> Format data/factory reset. **This will delete all of your files!**
+3. Return to the main menu and select Apply update -> Apply from ADB.
+4. On the host computer, run the command:
+```
+adb -d sideload /path/to/zip
+```
+replacing /path/to/zip with where you stored the crDroid zip file.
+It will most likely stop at 47%, and the phone will ask if you want to install any additional packages while in recovery.
+If you want to install Gapps or anything like that needing to be installed in recovery, do it now.
+Once done, go back to the main menu and select Reboot to system.
+
+You're done!
+
+### Manual update installation:
+
+* Step 1
+1. Download the crDroid Android zip file from [here](https://crdroid.net/pdx237/12)
+* Step 2
+On the phone, enter recovery mode by powering off the phone and holding Volume Down + Power. Once in recovery, select Apply update -> Apply from ADB and plug the phone into the computer.
+* Step 3
+On the host machine, sideload the ZIP by running:
+```
+adb -d sideload /path/to/zip
+```
+replacing /path/to/zip with where you stored the crDroid zip file.
+It will most likely stop at 47%, and the phone will ask if you want to install any additional packages while in recovery.
+If you want to install Gapps or anything like that needing to be installed in recovery, do it now.
+Once done, go back to the main menu and select Reboot to system.
+
+You're done!
