This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Say thank you¶
I love the idea of Open Source. TYPO3 and its community has given a lot to me, so I'm happy to give something back.
Nevertheless I have spent a lot of work and hours in developing my extensions. (https://extensions.typo3.org/?L=0&id=1&tx_solr%5Bq%5D=peter+benke)
So, if you would like to say thank you, don't hesitate to support me with a little donation ;-)
