I know that one of the biggest barriers for completely ditching my MacBook Pro for my Pixelbook was the ability to use ADB and fastboot (upgrading Android versions, flashing TWRP, factory resetting). ADB and fastboot are installed on later versions of Chrome OS; unfortunately, these versions are too old for devices like the Pixel 2 (XL) and there isn't a ton of information on how to get them updated and working properly.
As such, I created an installation script that will push the latest versions of the platform tools to the local binary directory and install a small wrapper script so you can use the commands as you normally would. The scripts should be fairly easy to read if you have a basic understanding of the command line, I have commented them so it's clear what is going on.
The installation script can be used to install the tools for the first time as well as upgrading to newer version as they come out. The changelog for each version can be found here.
Please see the README for the full instructions and let me know if you have any questions, enjoy!
