 # Sailfish on tucana
 
 This repository is for bugs and docs.
+
+# Installing
+
+You need a MIUI Android 10 vendor partition, I used [tucana_global_images_V12.0.3.0.QFDMIXM_20201026.0000.00_10.0_global](https://xiaomifirmwareupdater.com/miui/tucana/stable/V12.0.3.0.QFDMIXM/) - probably others will work.
+Boot into it at least once to verifiy the downgrade worker correctly.
+
+This is mainly for the vendor partition but any other device calibrations that could be done.
+
+Next you can install this Lineage 17.1 build: https://forum.xda-developers.com/t/deprecated-rom-10-unofficial-tucana-lineageos17-1.4196085/
+(or use mine, https://1drv.ms/u/s!Alh0arVfv0RwirZ7aGrClFPS1kXTqw?e=7JhQVY - the only difference is that mine uses the OSS kernel, but we will replace this next).
+
+Next install the alpha release (that is, you get all the [issues](https://github.com/sailfishos-on-tucana/Readme/issues): 
+You download the boot image and the bz2 file, install the img with twrp on the boot partition and for the bz2 do:
+```
+#!/bin/bash -x
+RELEASE=4.0.1.48
+EXTRANAME=${EXTRANAME:=-alpha}
+echo publishing $RELEASE$EXTRANAME
+sudo bunzip2 -vf sfe-tucana-$RELEASE$EXTRANAME.tar.bz2
+adb shell mkdir -p /data/.stowaways/sailfishos
+adb push sfe-tucana-$RELEASE$EXTRANAME.tar /sdcard/
+adb shell tar --numeric-owner -xf /sdcard/sfe-tucana-$RELEASE$EXTRANAME.tar -C /data/.stowaways/sailfishos
+```
