Install Java Runtime Environment (JRE)
Daffodil will run on Java 7 or newer. If you do not already have the Java Runtime Environment, it can be downloaded for free at https://java.com/en/download/.
Obtain The Latest Daffodil Release
Visit the Daffodil Artifacts Page to download the latest Daffodil stable or development releases.
Run Daffodil
After you have downloaded the latest Daffodil Release, you'll want to uncompress the files into a suitable location on your machine. The uncompressed directory contains a bin directory that contains two scripts: daffodil.bat for Windows, and daffodil for Linux. These files must be executed on the command line. See the Examples page to see how to execute and use the Daffodi CLI, and the Command Line Interface page for the in depth usage.
