Lucee documentation

Welcome to the official Lucee Server documentation website.

The documentation here aims to provide a thorough reference and guide to all things to do with the Lucee Server. You should hope to find reference material on both Lucee functions and Lucee tags as well as more in-depth articles in the Guides and tutorials section.

The documentation is an open source and community driven effort. It is also a constant work in progress and we're always open to input. You can find out more about contributing in the About the docs section.
