+how to use the apm reader for converting your data to NeXus using a Jupyter notebook. That notebook details also the commands how to convert data via command line calls. Note that not every combination of input from a supported file format and other, typically electronic lab notebook, input for the parser allows filling the required and recommended fields and attributes of the NXapm application definition.
+Therefore, you may need to provide an ELN file that contains the missing values in order for the
 validation step of the APM reader to pass.
