-## RTView
-
-> Attention: RTView is hidden behind a build flag. Enable with this cabal flag: `-f +rtview`.
-
-RTView is a real-time monitoring tool for Cardano nodes (RTView is an abbreviation for "Real Time View"), it is a part of `cardano-tracer` service. RTView provides an interactive web page where you can see different kinds of information about connected nodes (something like Grafana).
-
-For more details please [read its documentation](https://github.com/intersectmbo/cardano-node/blob/master/cardano-tracer/docs/cardano-rtview.md).
-
-RTView is not feature complete and is thus disabled by default. Being
-an experimental/optional component of `cardano-tracer` we will still
-guarantee it remains buildable and usable in its current state.
-
 ## Developers
 
 Performance and Tracing team is responsible for this service. The primary developer is [Baldur Blöndal](https://github.com/Icelandjack).
 
 ## Feedback
 
-Your bug reports and/or Feature Requests are welcome! Feel free to open a ticket in [this repository](https://github.com/intersectmbo/cardano-node/issues) with labels `RTView` and `tracing`.
