Welcome to Citus¶
Welcome to Citus’s documentation. Get started with Installation and then get an overview with the Quickstart. There is also a more detailed Tutorial that shows how to create a small but complete application with Citus. Common patterns are described in the Patterns for Flask section. The rest of the docs describe each component of Citus in detail, with a full reference in the API section.
Citus depends on the Jinja template engine and the Werkzeug WSGI toolkit. The documentation for these libraries can be found at:
