Why GitHub Pages
Understand what GitHub Pages is, why it suits learning content, and where its limits lie.
"Okay," Leela says, "so the pages are built from text. But where do they actually live? Who keeps the website running?"
Manjari puffs out her chest. "No one has to keep it running! That is the best part. The files live on GitHub, and GitHub serves them for us — for free."
What GitHub Pages Is
GitHub Pages is a free hosting service that serves static files straight from a GitHub repository. Every time new files are pushed, they can be built and published automatically — no servers to rent, no databases to configure, no midnight outages to fix.
"Static" just means the files are finished before anyone visits: HTML, CSS, and JavaScript, ready to serve as-is. There is no application running behind the scenes to keep warm.
Why It Suits Learning Content
Serving a public site from GitHub Pages costs nothing
Files are served through a global CDN
Secure connections, no certificate paperwork
Point your own domain at it in minutes
Every published version matches a commit
Push to the repository, and the site updates itself
Lessons, tutorials, documentation, and reference material are a natural fit: they are mostly text, they change gradually, and they benefit enormously from version history — "what did this page say last month?" is a question git answers instantly.
How Publishing Works Here
This site uses a GitHub Actions workflow: every change pushed to the repository triggers a build, and the finished site is published automatically.
Because this is a public repository, the site is public too — which is exactly right for a learning demo. Free GitHub Pages hosting is intended for public content. Private or sensitive material belongs elsewhere.
Being Honest About Limits
GitHub Pages serves static files only. It cannot run a database, handle logins, process payments, or keep secrets — and it should never be given credentials or private data. When a project needs an application backend, that is a different architecture, for a different purpose.
This demo is exactly what it claims to be: a public showcase of how MDX content can be published to the web with a small, transparent, free toolchain.
GitHub Pages hosts static files free, fast, and automatically — a perfect match for learning content that lives in a public repository and changes through version control.
