The use case: how Reflag deploys GitBook
Reflag, a feature management tool for B2B SaaS, uses GitBook for its developer documentation, customizing the design to match its brand. It syncs docs from multiple SDK repositories into a central GitHub repository via Git Sync and GitHub Actions, and reviews changes through GitBook or GitHub pull requests.
