-The data streaming system is being built as a requirement for HRPD-X and possibly SANDALS-II, separate (and complementary) to the `MNeuData` project. It is architecturally similar to the system that the ESS uses to take data (neutron events, sample environment, and anything else that we can throw into a streaming platform) and write it to file. Previously ISIS aided development to the ESS' streaming pipeline as part of an in-kind project. The system will replace the ICP at ISIS.
+The data streaming system is being built as a requirement for HRPD-X and possibly SANDALS-II, separate (and complementary) to the `MNeuData` project. HRPD-X, SANDALS-II and other future instruments will not have a traditional DAE2/DAE3 as they are now obselete.

 In general this works by producing both neutron events and histograms, sample environment data, and other diagnostic data into a [Kafka](https://kafka.apache.org/) cluster and having clients (consumers in Kafka lingo!) that either view data live and act on it or write the data to a nexus file. Additional information can be found [here](http://accelconf.web.cern.ch/AccelConf/icalepcs2017/papers/tupha029.pdf) and [here](https://iopscience.iop.org/article/10.1088/1742-6596/1021/1/012013).

 This comprises of a few different consumers and producers: 
 - [`azawakh`](https://github.com/ISISComputingGroup/azawakh) - This is a soft IOC which provides `areaDetector` views, spectra plots and so on by consuming events from the cluster and displaying them over EPICS CA/PVA.
 - [`borzoi`](https://github.com/ISISComputingGroup/borzoi) - This is also a soft IOC which is more or less a drop-in replacement for the ISISDAE. It provides an interface that several clients (ie. [genie](https://github.com/ISISComputingGroup/genie), [ibex_bluesky_core](https://github.com/ISISComputingGroup/ibex_bluesky_core), [ibex_gui](https://github.com/ISISComputingGroup/ibex_gui)) talk to to start/stop runs and configure streaming electronics. `borzoi` will send UDP packets to the streaming electronics to configure it. 
-- [`BSTOKAFKA`](https://github.com/ISISComputingGroup/BSKAFKA) - This configures the `forwarder` with the blocks that are in an instrument's current configuration, as well as other PVs which will either get written to a file or archived for eg. the log plotter.
