[TYPO3-english] enabling RSS feed with tx_news

[Brandon Walsh]

I am fairly new to TYPO3 and am having trouble following the instructions here:

https://docs.typo3.org/typo3cms/extensions/news/3.0.0/Main/Administration/Rss/Index.html

What I need to do is to create an RSS feed of the content currently being displayed by News plugin. As I am a new user of TYPO3, it is not clear to me where I need to put the code that's given in the RSS tutorial linked above. Your guidance would be much appreciated.
