README.md

*Tart* is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon.
Built by CI engineers for your automation needs. Here are some highlights of Tart:

* Tart uses Apple's own `Virtualization.Framework` for [near-native performance](https://browser.geekbench.com/v5/cpu/compare/20382844?baseline=20382722).
* Push/Pull virtual machines from any OCI-compatible container registry.
* Use Tart Packer Plugin to automate VM creation.
* Easily integrates with any CI system.

Many companies are using Tart in their internal setups. Here are just a few of them:

**Note:** If your company or project is using Tart please consider [sharing with the community](https://github.com/openai/tart/discussions/857).
