# GitHub Actions Runner [](https://github.com/actions/runner/actions) The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the [hosted virtual environments](https://github.com/actions/virtual-environments), or you can [self-host the runner](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners) in your own environment. ## Get Started For more information about installing and using self-hosted runners, see [Adding self-hosted runners](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/adding-self-hosted-runners) and [Using self-hosted runners in a workflow](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/using-self-hosted-runners-in-a-workflow) ## Download and Install  **Windows**: [Prerequisites](docs/start/envwin.md) | [Download](https://github.com/actions/runner/releases)  **macOS**: [Prerequisites](docs/start/envosx.md) | [Download](https://github.com/actions/runner/releases)  **Linux**: [Prerequisites](docs/start/envlinux.md) | [Download](https://github.com/actions/runner/releases) ## Documentation and Resources - 📖 **[Contributing Guide](docs/contribute.md)** - Development setup, building, and testing - 🔧 **[Automation Scripts](docs/automate.md)** - Automate runner setup and configuration - 🏗️ **[Architecture Decision Records](docs/adrs/README.md)** - Important architectural decisions - ⚙️ **Platform Prerequisites:** [Linux](docs/start/envlinux.md) | [Windows](docs/start/envwin.md) | [macOS](docs/start/envosx.md) ## Support and Community Thank you for your interest in this repository.
