The use case: how Tuum deploys GitBook
Tuum, a core banking platform, uses GitBook to host its customer-facing documentation, including developer docs, release notes and the API reference. The API specs are published to GitBook automatically after each release through a pipeline that uses the GitBook API, and GitBook's style guide and content gaps features help a small team keep docs consistent.
In the customer’s words
Our API docs now run on a fully automated process, without any human intervention.Other companies using GitBook

Tuum generates its OpenAPI specifications from the codebase. Each product team owns its part of the spec, including the descriptions for endpoints and parameters, and the technical writers set the guidelines for how those are written and ordered.
