repo sync

Then add these projects to .repo/manifest.xml:

<project path="device/xiaomi/perseus" name="mauronofrio/android_device_xiaomi_perseus" remote="github" revision="android-9.0" />

Finally execute these:

. build/envsetup.sh
lunch omni_perseus-eng

To test it:

fastboot boot out/target/product/perseus/recovery.img
