py-init

A small python based initialization tool to kickstart Raspberry Pi configuration.

The main aim for this tool is to automate configuration steps that I usually take, everytime I set up a new Raspberry Pi. I hope it helps you too.

manual

This tool needs python3 installed.

1. Clone this repository
2. Change the settings you need in the config.json, remove the settings you don't want to configure from it. (In case you screw up, there is a copy under config.json.default)
3. Run the tool using the following command

   sudo ./configure
