In GitHub Pages, the default site title is often taken from the repository name. This can be overridden to display a custom title in the page header.
Most GitHub Pages sites (especially those using Jekyll) render the title from the site.title variable. If it is not defined, the system falls back to the repository name.
To set a custom title, define it in the _config.yml file:
title: Tech Notes
description: Personal collection of technical notes
This will replace the default repository-based title in the site header.
