 ## Dependencies
 
- * curl - required, for android-prepare-vendor
- * e2fsprogs (debugfs) - required, for android-prepare-vendor
- * git - required, for android-prepare-vendor
  * protobuf-compiler (protoc) - optional, see below
  * python3-protobuf - required
 
 ## Usage
 
-Download the [carrier ID database](https://source.android.com/devices/tech/config/carrierid) from AOSP.
-
-    ./download_carrier_list.sh
-
-Download a [Pixel factory image](https://developers.google.com/android/images) and extract the CarrierSettings protobuf files. This script will download android-prepare-vendor and copy the directory `CarrierSettings` containing the protobuf files.
