+Units
+=====
+
+``metatrain`` will always work with the units as provided by the user, and all logs will
+be in the same units. In other terms, ``metatrain`` does not perform any unit
+conversion. The only exception is the logging of energies in ``meV`` if the energies are
+declared to be in ``eV``, for consistency with common practice and other codes.
+
+Although not mandatory, the user is encouraged to specify the units of their datasets
+in the input files, so that the logs can be more informative and, more importantly, in
+order to make the resulting exported models usable in simulation engines (which instead
+require the units to be specified) without unpleasant surprises.
