+## Features
+
+This module comprises the following features:
+
+* Adds `BurstyApplication` and `BurstSink` as ns-3 applications: they allow to model complex applications sending large data packets over UDP sockets, fragmenting them into bursts of smaller packets, and reassembling the packets at the receiver, if possible
+* A tracing system allows to obtain burst-level and fragment-level information at both the transmitter and receiver side
+* Models a Virtual Reality traffic source
+* 10 of the acquired VR traffic traces can be found in this repository and can be used directly in a simulation, using the `TraceFileBurstGenerator`
+* Additional traffic models can be implemented by simply extending the `BurstGenerator` interface
+
+Future releases will aim to:
+* Improve, add, and diversify the real VR traffic traces
+* Model second-order statistics for VR traffic
+* Include a head-rotation model, coupled with the VR traffic generator
+* Optionally include sound traffic in the VR traffic generator, other than video traffic
+* Optionally include uplink/downlink control packets for the VR traffic model
+* Improve `BurstSink` to also include some form of forward error correction
+
+More information can be found in the reference paper(s).
