Or, check our screencasts:

Matey is a YARRRML editor that allows you to try out your YARRRML rules. Behind the scenes, the YARRRML rules are converted to RML rules and executed by the RMLMapper. Matey is made for people who want to try out YARRRML without installing anything, in your browser. You can add your input data on the left (yellow box), write your YARRRML rules on the right (green box) and get the generated RDF (purple box). YARRRML also supports Targets which allows you to have multiple RDF outputs, you can find all generated RDF outputs in the dropdown menu of the purple box, together with the RML rules. Some examples are available as well to see how Matey works and get you started quickly. You can load those below by selecting one in the dropdown and click on the 'Load Example' button. Once loaded, you can edit them as you wish. A tutorial is available at https://rml.io/yarrrml/tutorial/getting-started/.

We are conducting a user study to evaluate and improve Matey in the future regarding its user experience and usability, if you have a few minutes, please leave your feedback here.
