# Integrating with your CI environment

Dagger can be used with any CI environment (no migration required) and has two important advantages which make the overall experience less error-prone and more efficient:

1. You don't write YAML, you write [CUE](https://cuelang.org/) - typed configuration with built-in formatting
2. Configuration is executed in [BuildKit](https://github.com/moby/buildkit), the execution engine at the heart of Docker

This makes any CI environment with Docker pre-installed work with Dagger out of the box.
We started with [CI environments that you told us you are using](https://github.com/dagger/dagger/discussions/1677).
We will configure a production deployment for the same application that we covered in the previous page.

:::note
If you cannot find your CI environment below, [let us know via this GitHub discussion](https://github.com/dagger/dagger/discussions/1677).
