+- Downloading factory images and full OTA packages
+- Generating a list of proprietary files
+- Resolving overridden build rules and building modules from source (when possible)
+- Extracting, converting, and mounting factory images
+- Extracting proprietary files
+- Extracting bootloader and radio firmware
+- Finding and adding missing system properties
+- Overriding build fingerprint to help pass SafetyNet
+- Adding missing SELinux policies
+- Adding missing HALs to vendor interface manifests
+- Generating resource overlays for device configs
+- Fixing privileged app signing certificates referenced in SELinux policies
 
-describe the command here
+Google Pixel devices will benefit from the most automation, but several features can still be used to ease manual bringup on other devices:
 
-```
-USAGE
-  $ adevtool hello [FILE]
+- Check SELinux policies to identify apps that should be presigned
+- Compare a built system against stock images to find missing files, properties, and vendor interface declarations
+- Resolving overridden build rules from build warnings
+- Listing system files relevant to bringup (in all partitions)
+- Extracting files from proprietary-files.txt **up to 10x faster than LineageOS extract-utils**
 
-OPTIONS
-  -f, --force
-  -h, --help       show CLI help
-  -n, --name=name  name to print
