go install github.com/helm/chart-testing@latest
```

### macOS
```bash
go install github.com/helm/chart-testing@latest
```

### Windows
```bash
go install github.com/helm/chart-testing@latest
```

## System Requirements & Architecture

- **Runtime Dependencies**: Go >= 1.21 runtime environment
- **Architecture**: x86_64, ARM64 (Apple Silicon & Graviton)

## How It Works
chart-testing coordinates its core functionality through a modular Go pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.

## Production Use Cases
### Production System Integration
Embed chart-testing into Go backend services to handle core application logic.

### CI/CD Automated Pipelines
Run automated validation, builds, and integration suites during deployments.

### Developer Tooling & Workflows
Accelerate developer onboarding with pre-configured project utilities.

### Open Source Extension
Fork and customize internal modules under the repository's open Apache-2.0 license.

## Target Audience
Developers and engineering teams building with Go, seeking reliable, tested, and actively maintained tooling for production workloads.

## Strengths
- Active community backing with 1,645 GitHub stars and verified adoption.
- Permissive open-source distribution under the Apache-2.0 license.
- Built in Go for high execution speed and developer familiarity.
- Cross-platform compatibility across modern Linux, macOS, and Windows environments.
- Clean modular design allowing flexible configuration and pipeline integration.

## Considerations
- Requires familiarity with Go and modern CLI workflows.
- Ecosystem extensions may require manual configuration depending on environment constraints.
- Active development roadmap means breaking API changes may occur across major versions.
