Murali3007/tertragon-updated-site ? reverse-engineered prompt

Build me a clean documentation site for Tetragon that works as a user guide and feels easy to browse.

I want a simple homepage, a docs section with clear navigation, and a sidebar that helps people find setup, usage, and reference material quickly. Make it readable on desktop and mobile, keep the design polished but not flashy, and use the existing docs content where it makes sense. It should be easy to add or update markdown pages later, and any images or static files should be handled neatly.

If there are small improvements that make the guide easier to use, like better headings, search friendly structure, or a nicer landing page, go ahead and do those. Use the current project setup, and if you need to check the latest docs for anything, look them up online.
