using the new bootloader.
+## Flashing Logic
+
+Fastboot binary will follow directions listed out fastboot-info.txt
+build artifact for fastboot flashall && fastboot update comamnds.
+This build artifact will live inside of ANDROID_PRODUCT_OUT &&
+target_files_package && updatepackage.
+
+
+The currently defined commands are:
+
+ flash %s Flash a given partition. Optional arguments include
+ --slot-other, {filename_path}, --apply-vbmeta
+
+ reboot %s Reboot to either bootloader or fastbootd
+
+ update-super Updates the super partition
+
+ if-wipe Conditionally run some other functionality if
+ wipe is specified
+
+ erase %s Erase a given partition (can only be used in conjunction)
+ with if-wipe -> eg. if-wipe erase cache
## Client Variables
