# Welcome to the Zulip documentation! Welcome! Zulip's documentation is split into four parts: - [Help center documentation](https://zulip.com/help), for users and administrators of Zulip organizations. - [Installation documentation](production/install.md), for installing and maintaining a production self-hosted Zulip installation. - [API documentation](https://zulip.com/api/), for writing integrations or bots using the Zulip API. - [Contributor documentation](contributing/contributing.md), for developing the Zulip software, translating, submitting bug reports, or making other contributions to the project. Zulip has well over 150,000 words of documentation. If you can't find what you're looking for, please [let us know](https://zulip.com/development-community/)! Further information on the Zulip project and its features can be found at . This site contains our installation and contributor documentation.
