+topic|string|Yes| The kafka topic to listen to for data. |
+source|string|Yes| The source (name) of the data to be written. |
+writer_module|string|Yes| The identifier of this writer module (i.e. "ad00"). |
+cue_interval|int|No| The interval (in nr of events) at which indices for searching the data should be created. Defaults to 100 million. |
+chunk_size|int|No| The HDF5 chunk size in nr of elements. Defaults to 1M. |

+Typically, the `$AREADET$` placeholder is replaced at runtime by NICOS.
+Alternatively, it can contain an array of values corresponding to width and height.

Writer modules for the various FlatBuffer schemas give the file-writer the
ability to parse the FlatBuffers and write them to HDF5.
-
-The actual parsing of the different FlatBuffer schemas and conversion to HDF5 is
-handled by modules which register themselves via the `FlatbufferReaderRegistry`
-and `HDFWriterModuleRegistry`. For an example, please search for `Registrar` in
-`src/schemas/hs00/`. Support for new schemas can be added in the same way.
