This is divided into 2 parts separated by categories:
- categories “Plug-ins *” contain detailed descriptions for all jRQL plug-ins easy to setup and useable even without Java knowledge
- categories “API *” contains a tutorial Java developers should use to start using the jRQL API
If you might be interested in both, I would recommend the jRQL presentation (German) I held Feb 2010 on the Usergroup Conference in Munic, Germany.
Please refer to the page Download plug-ins setup where you can download the setup routine and are guided through the installation steps. There is an import wizard for the plug-ins you want to use and an tool to support your work with RQL interactively.
If you want to get in touch with the underlaying jRQL API, you should download and install the pre-configured Eclipse project and start reading the tutorial posted in categories starting with API.
