+  specified with the ``datatype`` keyword to `cfdm.write`
+  (https://github.com/NCAS-CMS/cfdm/issues/16).

+The ``cfdm`` package implements the CF data model
+(https://doi.org/10.5194/gmd-10-4619-2017) for its internal data
+structures and so is able to process any CF-compliant dataset. It is
+not strict about CF-compliance, however, so that partially conformant
+datasets may be ingested from existing datasets and written to new
+datasets. This is so that datasets which are partially conformant may
+nonetheless be modified in memory.
 
 The central element defined by the CF data model is the **field
 construct**, which corresponds to a CF-netCDF data variable with all
 of its metadata.
