## Overview

This YAML viewer renders configuration files locally in your browser. YAML is widely used for app configs, Docker Compose, Kubernetes manifests, and CI/CD pipelines. Pick a sample or choose your own .yaml file to inspect keys, lists, and nested structure with proper indentation.

## When to use

- You received a YAML config file and need to read it without an editor.
- You want to check a Docker Compose or Kubernetes manifest quickly.
- You are on a device without a code editor and need to browse a .yml file.

## How it works

- Select a built-in sample or choose your own .yaml or .yml file.
- The viewer parses the YAML and renders it with syntax highlighting in the browser, with no upload.
- Inspect the structure, then switch samples or load another file any time.

## Use cases

- Reviewing app, Docker Compose, and Kubernetes configuration files.
- Inspecting CI/CD pipeline definitions.
- Browsing nested YAML data on any device.

## Samples

- **Simple App Config**: A minimal YAML application configuration with nested keys and lists
