 # fdreadoutlibs - Far Detector readout libraries
-Collection of Far Detector FrontEnd specific readout specializations.
+Collection of Far Detector FrontEnd specific readout specializations. This includes type definitions to be used with the implementations in `readoutlibs` and frontend specific specializations (i.e. frame processors or software hit finding). It is the glue between `readoutlibs` and `readoutmodules` that specifies types and implementations for the use of `readoutlibs` that can then be imported by `readoutmodules` to be initialized in the `DataLinkHandler` module.
 
 ## Building and setting up the workarea
 
-How to clone and build DUNE DAQ packages, including `readout`, is covered in [the daq-buildtools instructions](https://dune-daq-sw.readthedocs.io/en/latest/packages/daq-buildtools/). You should follow these steps to set up your workarea that you can then use to run the following examples.
+How to clone and build DUNE DAQ packages, including `readout`, is covered in [the daq-buildtools instructions](https://dune-daq-sw.readthedocs.io/en/latest/packages/daq-buildtools/). For examples on how to run the standalone readout app, take a look at the `readoutmodules` documentation.
 
+## Frontends and features provided by `fdreadoutlibs`
+The following frontends and features are provided by this package:
+* *Daphne*: Frame processor and request handler to be used with the SkipList latency buffer.
+* *SSP*: Only frame processor
+* *WIB*: Frame processor for `WIB`, software and hardware `WIB` TPs. Implementation of avx based software hit finding (software tpg) for `WIB`
+* *WIB2*: Only frame processor
