AI Summary: Implement a print-friendly version of LeafWiki pages by creating a dedicated print stylesheet that hides the header and sidebar, and adding a 'Print' button to trigger the browser's print dialog. This will allow users to easily generate PDF versions of individual wiki pages using their browser's built-in functionality.

AI Summary: Create a new documentation file detailing how to install and run LeafWiki on a Raspberry Pi, including considerations for dependencies, file permissions, and optional systemd setup. The documentation should be clear, concise, and suitable for a blog post.
