+Beamline module for use with the simulated AreaDetector and motors.
+These devices are simulated at the EPICS level, enabling testing of
+dodal and ophyd-async against what appear to be "real" signals.
+
 Usage Example
 -------------
 
 Start the simulated beamline by following the epics-containers tutorial at
 https://epics-containers.github.io/main/tutorials/launch_example.html
+And ensure that the signals are visible:
+
+```sh
+export EPICS_CA_ADDR_LIST=127.0.0.1
+```
 
 How to use the devices in a plan:
