 ## Explore feeds section
 You can help to improve our explore feeds section by [providing more feeds](https://github.com/nextcloud/news/tree/master/docs/explore)
 
-## Fulltext configurations
-
-Nextcloud News uses [picoFeed web scrapers](https://github.com/miniflux/picoFeed/blob/master/docs/grabber.markdown). Simply create a new configuration file if needed and open a pull request on their repository. The News app syncs regularly with the most recent changes.

 ## Development
-
 In general it's a good idea to **first create an issue where you explain why, what and how** you want to make a change **before writing any code**.
 
 That way we can talk about the problem first and discuss the implementation (and of course help you with your code)
 
 ### How to set up a development environment
-
 To get started after [cloning the repository](https://github.com/nextcloud/news#installing-from-git-development-version), install the [build dependencies](https://github.com/nextcloud/news#development-dependencies) and run:

 ### Coding Style Guidelines
-
 The PHP code should all adhere to [PSR-2](https://www.php-fig.org/psr/psr-2/).
 *Note that this is a different codestyle than nextcloud itself uses.*
 To test the codestyle you can run `make phpcs`.
