I removed the navigation links you pasted because they look like page navigation (previous/next/related links) rather than main content. I can't transform anything further without the actual page body to convert into GitBook-optimized Markdown.
Please paste the main content of the page you want imported (the article body, headings, code blocks, images, FAQ, lists, etc.). I'll convert it following the GitBook guidelines (turn package-manager blocks into tabs, convert long numbered steps into a stepper, transform FAQs to expandables, remove unrelated nav, etc.).
