Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
Use this skill when you need when the user wants to create step-by-step technical tutorials, quickstarts, or code walkthroughs. Trigger phrases include "tutorial," "quickstart," "getting started guide," "walkthrough," "step by step," "how to guide," "hands-on guide," or "code tutorial.".
This skill helps you create step-by-step tutorials that actually work. Covers prerequisite handling, progressive complexity, troubleshooting sections, and creating those satisfying "it works!" moments.
Be explicit. Don't make developers guess what they need.
## Prerequisites
Before starting, make sure you have:
| Requirement | Version | Check Command |
|-------------|---------|---------------|
| Node.js | 18+ | `node --version` |
| npm | 9+ | `npm --version` |
| Git | Any | `git --version` |
You should also be comfortable with:
- Basic JavaScript (variables, functions, async/await)
- Command line basics (cd, mkdir, running commands)
- REST API concepts (HTTP methods, JSON)

Make setup foolproof:
## Setting Up Your Environment
### 1. Create Project Directory
\`\`\`bash
mkdir my-awesome-project
cd my-awesome-project
\`\`\`
### 2. Initialize the Project
\`\`\`bash
npm init -y
\`\`\`
You should see output like:
\`\`\`json
{
"name": "my-awesome-project",
"version": "1.0.0",
...
}
\`\`\`
### 3. Install Dependencies
\`\`\`bash
npm install express dotenv
\`\`\`
### 4. Verify Installation
\`\`\`bash
node -e "require('express'); console.log('Express installed!')"
\`\`\`
Expected output: `Express installed!`
