• A working ooRexx 5.0 installation.
• If you intend to install CGI support, you will also need a working Apache installation with access to ooRexx 5.0 and to Pandoc (Apache 2.4 is recommended).

• Go to the downloads page, download the most current version of the Rexx Parser, and unzip it in a directory of your choice.

For a CGI installation, follow these steps:

• In your Apache configuration, define an action directive pointing to your version of CGI.markdown.rex:

  Action RexxCGIMarkdown [path]CGI.markdown.rex
  

• You can then use whatever mechanism you prefer to associate Markdown files with the action handler you just defined.

  <Files *.md>
    SetHandler RexxCGIMarkdown
  </Files>
  

• Restart Apache.

Proceed to the first steps page to check that your installation works properly.
