Hi,

We have several examples of text and RSS crawl at [Tutorials]:Lower Thirds\
In these examples, you can add a new source RSS or Text file in the dashboard. Or if you drag and drop these example compounds into another compound, then you can add a new source by selecting the drag drop-ed compound.
Feel free to ask anything about those examples if you are stuck with them.

If you don't have the tutorials folder, then you can download the Tutorials and Samples package from here: https://my.aximmetry.com/User/MyDownloads 

Warmest regards,
