Config

Define global metadata for your documentation

Vocs uses a configuration file (vocs.config.ts) to define global metadata for your documentation. This includes things like the site title, description, logo, sidebar, and more for your project.

Initialize Config File

The Vocs config can be defined in a vocs.config.ts file at the root of your project.
