## Configuring Eva

- [Configuration](https://docs.evafactory.co/configure/configuration): Where Eva reads configuration from, how the layers resolve, every key you can set, and how to ask Eva which layer a value actually came from.
- [Models](https://docs.evafactory.co/configure/models): Set the model for one run with a flag, inside a session with the model command, or permanently with the model key. The Catalog holds what Eva knows.
- [Plugins](https://docs.evafactory.co/configure/plugins): Every capability in Eva is a plugin. Turn one on or off in config or with a flag, give it options, and swap a default — the trace sink included.
- [Providers](https://docs.evafactory.co/configure/providers): Eva ships Anthropic and OpenAI, and talks to any OpenAI-compatible endpoint you name in config. One API key each, and retries you can tune.
- [Trust and the .eva directory](https://docs.evafactory.co/configure/trust): A repository can ship a .eva directory with a team's Eva setup. Eva reads it only after you run eva trust there, because the grant is yours to give.
