We built our documentation for Courier using Docusaurus, addressing pain points such as limitless collaboration, versioning, link validation, and localization. We moved away from ReadMe after finding it inconvenient due to its flat file structure and lack of Git integration. Docusaurus offered a scalable solution with features that catered to our growing team's needs, including collaborative editing, API documentation, search functionality, and customization options. By leveraging Markdown, MDX integration, and plugins, we created a user-friendly documentation platform that can be easily updated and maintained by the team, utilizing GitHub for version control and Vercel Functions for proxying API requests. Our goal now is to utilize Docusaurus's localization feature and make our documentation open-source to encourage external contributions.
