Discover all rich authoring capabilities in Zerho.

Markdown Superpowers #

Discover the rich authoring capabilities available in Zerho for technical documentation.

Polyglot Synchronized Code Groups (`::: code-group`) #

Group multi-platform installation commands or code examples with automatic client-side synchronization:

deno add jsr:@zerho/zerho
GLOBAL SELECTION SYNC

When the user picks pnpm or Deno, Zerho remembers this preference in localStorage and updates every code group across the documentation instantly.

VitePress Callouts & GitHub Alerts #

Zerho supports standard callout containers:

INFORMATION

Electric cyan container for general notes, context, or explanations.

PRO TIP

You can embed inline code, bold text, and links inside any callout container.

WARNING

Modifying runtime flags can change module resolution behavior in Deno 2.

DANGER

Never expose sensitive credentials or private API keys in client-side code.

GitHub flavored alerts are also automatically mapped:

NOTE

This alert was written using standard GitHub > [!NOTE] syntax.

TIP

Both > [!TIP] and > [!IMPORTANT] are supported interchangeably.
