# The Catalyst platform

This section covers what every Catalyst user shares, whatever they build: how Catalyst is hosted, how organizations, projects, and identities work, how to operate the platform, and the full reference for the CLI, the APIs, and the component specs.

Platform operators will find hosting and operations here.
Developers will mostly come here for local development tools and reference material.
