• Prerequisites: Java 8
• Installing
• Building output
• For developers
• License

• To build DITA-OT, you’ll need Java Development Kit (JDK), version 8 or newer
• To run DITA-OT, the Java Runtime Environment (JRE) is sufficient

You can download the Oracle JRE or JDK from oracle.com/technetwork/java.

1. Download the distribution package from dita-ot.org/download.
2. Extract the contents of the package to the directory where you want to install DITA-OT.

On macOS, you can also install DITA-OT using the Homebrew package manager:

brew install dita-ot

Homebrew will automatically download the latest version of the toolkit, install it in a subfolder of the local package Cellar and symlink the dita command to /usr/local/bin/dita.

You can generate output using the dita command-line tool included with DITA Open Toolkit.

1. On the command line, change to the bin folder of the DITA-OT installation directory:

   cd path/to/dita-ot-dir/bin
   

2. Run the dita command to generate output:

   dita --input=input-file --format=format [options]
   

   where:

   • input-file is the DITA map or DITA file that you want to process
   • format is the output format (or “transformation type”)

See the documentation for arguments and options.
