Quick Start Guide - Create Documentation in 4 Steps

1. Create a new documentation project directory:

   mkdir mydocs && cd mydocs

2. Initialize your documentation site:

   okidoki init

   Automatically creates project structure with configuration files and sample content.

3. Build your static documentation site:

   okidoki generate

   Generates optimized HTML, CSS, and JavaScript files for deployment.

   Tip: Use okidoki openapi -i your-api-spec.yaml to automatically generate API documentation from OpenAPI/Swagger files.

4. Preview your documentation locally:

   npx serve dist

   Your documentation website will be available at http://localhost:3000

   Alternative web servers: You can use any static file server - npx node-static dist, python -m http.server, or deploy to GitHub Pages, Netlify, Vercel, etc.
