MDX is useful when a normal markdown post needs one tiny interactive or reusable UI block.

Why I use it for Linux notes

I keep most posts in plain markdown, but MDX is great for repeated checklists.

• Confirm backups are healthy.
• Run package updates with release notes open.
• Reboot only after checking running services.

Keep MDX boring

Use MDX for small reusable fragments, not whole app logic. The cleaner your content files stay, the easier they are to maintain.
