If you already have locally-installed copies of Ant and the other required tools, install either the minimal or standard package.

1. Download the minimal or standard package from SourceForge.

   Package	File name
   Minimal	DITA-OT2.0.M3_minimal_bin.zip
   Standard	DITA-OT2.0.M3_standard_bin.zip

   For production use, we recommend that you use the latest stable release.
2. Extract the contents of the package into an installation directory.
   For example, C:\pkg\DITA-OT2.0.M3.
3. Verify that the JAVA_HOME environment variable is set.

   set JAVA_HOME=<JRE_dir>

4. Verify that the ANT_HOME environment variable is set.

   set ANT_HOME=<Ant_dir>

5. Verify that the PATH environment variable includes the Java and Ant executable files.

   set PATH=%JAVA_HOME%\bin;%ANT_HOME%\bin;%PATH%

6. Set the DITA_HOME environment variable to point to the DITA-OT installation directory.

   set DITA_HOME=<DITA-OT_dir>

7. Set up the CLASSPATH environment variable.

   set CLASSPATH=%DITA_HOME%\lib\dost.jar;%CLASSPATH%
   set CLASSPATH=%DITA_HOME%\lib;%CLASSPATH%
   set CLASSPATH=%DITA_HOME%\lib\resolver.jar;%CLASSPATH%
   set CLASSPATH=%DITA_HOME%\lib\commons-codec-1.8.jar;%CLASSPATH%

8. Optional: If you use Ant, version 1.8 or later, set up the CLASSPATH environment variable to include Apache Xerces.

   set CLASSPATH=<xerces_dir>\xercesImpl.jar;<xerces_dir>\xml-apis.jar;%CLASSPATH%

9. Set up the XSLT processor:
   Set up the CLASSPATH environment variable to include the Saxon JAR files, for example:

   set CLASSPATH=<saxon_dir>\saxon9.jar;<saxon_dir>\saxon9-dom.jar;%CLASSPATH%

   Set up the ANT_OPTS environment variable, for example:

   set ANT_OPTS=%ANT_OPTS% -Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl

10. Optional: For index processing, set up ICU for Java.

    set CLASSPATH=<icu4j_dir>\icu4j.jar;%CLASSPATH%

11. Optional: For JavaHelp, set the JHHOME environment variable.

    set JHHOME=<javahelp_dir>

12. Optional: For HTML Help, add the installation directory for the HTML Help Workshop to the local.properties file as the hhc.dir property.

    hhc.dir=C:\\Program Files (x86)\\HTML Help Workshop

13. Optional: For PDF output, set up the XSL-FO processor:

    Processor	Action
    FOP	Add the FOP installation directory to the local.properties file as the fop.home property, for example: fop.home=C:\\Program Files\\fop
    RenderX	Add the RenderX installation directory to the local.properties file as the xep.dir property, for example: xep.dir=C:\\Program Files\\xep
    Antenna House	Add the AH Formatter installation directory to the local.properties file as the axf.path property, for example: axf.path=C:\\Program Files\\AHFormatterV6

14. Test the DITA-OT installation by transforming the sample files.
    The samples\ant_sample directory contains Ant scripts designed to build various output formats.

    C:\DITA-OT2.0.M3>ant -f samples\ant_sample\sample_all.xml

    The generated output is written to the DITA-dir\out\samples directory. The following output formats are generated:

    • Docbook
    • Eclipse help
    • HTML Help
    • ODT
    • JavaHelp
    • PDF
    • TocJS
    • TROFF
    • XHTML
