Welcome to Tigerlings!

TigerBeetle is the financial transactions database built for unparalleled performance and mission-critical safety.

This project is an interactive tutorial that teaches you how to use TigerBeetle by fixing small scripts. Each script has some small error that you'll need to correct -- but don't worry, we'll explain everything you need to know!

This project was directly inspired by the Ziglings and rustlings projects.

git clone https://github.com/tigerbeetle/tigerlings.git
cd tigerlings
./run.sh

The run.sh script runs each exercise, one at a time, and stops at the first broken one.

You can get started with exercise 000_download.sh, which, as you might guess, helps you download TigerBeetle.

Once you've fixed the download script, run run.sh again to have it go to the next exercise.

Happy learning!

If you have questions about any of the exercises, feel free to open an issue on this repository or ask a question in the TigerBeetle Slack. We're here to help!
