# Logos ecosystem repositories

#### Review the key repositories across the logos organisations.

The Logos project is organised into several GitHub organisations, each focused on one part of the system. This page highlights the most important repositories for understanding the project and getting started with development. The selection is curated rather than exhaustive.

## Orientation and contribution resources

These repositories explain what Logos is building and how to take part, with no code to run.
