Language & theme
Switch between English/Vietnamese and light/dark/system theme.
Pegasus supports English and Vietnamese, plus light, dark, and system theme modes.

Use the Language control to switch between:
- English
- Tiếng Việt
Docs URLs mirror one-to-one: /en/docs/... maps to /vi/docs/....
Theme#
Use Theme to choose:
- Light — always light mode.
- Dark — always dark mode.
- System — follows your operating system/browser preference.
If language switching 404s#
That usually means a docs page exists in one locale but not the other. Report the broken URL so the mirrored page can be added.
