# Requirements

DITA-OT 2.2 or newer is required; earlier versions of DITA-OT do not have the required extension points. Some LwDITA features require a newer DITA-OT version.

# Install

See [DITA-OT plug-in registry](https://www.dita-ot.org/plugins#!org.lwdita) for `org.lwdita` plug-in.

The `dita` command line tool requires no additional configuration. Running DITA-OT using Ant requires adding plug-in contributed JAR files to `CLASSPATH` with e.g. `-lib plugins/org.lwdita`.
