 problem by also fetching the parent work, which would be the whole symphony in
 this example.
 
-It uses the ``mb_workid`` tag to retrieve the *parent work* and stores the
-``mb_workid`` as ``parentwork_workid_current``. When one executes 
-``beet parentwork`` it checks if ``mb_workid`` has changed by comparing it
-with ``parentwork_workid_current``, if it has changed or if ``force`` is
-enabled it fetches the *parent work* again.
+The plugin can detect changes in ``mb_workid`` so it knows when to re-fetch
+other metadata, such as ``parentwork``. To do this, when it runs, it stores a
+copy of ``mb_workid`` in the bookkeeping field ``parentwork_workid_current``.
+At any later run of ``beet parentwork`` it will check if the tags
+``mb_workid`` and ``parentwork_workid_current`` are still identical. If it is
+not the case, it means the work has changed and all the tags need to be
+fetched again.
 
 This plugin adds six tags:
 
 - **parentwork**: The title of the parent work.
-- **mb_parentworkid**: The musicbrainz id of the parent work.
+- **mb_parentworkid**: The MusicBrainz id of the parent work.
 - **parentwork_disambig**: The disambiguation of the parent work title.
 - **parent_composer**: The composer of the parent work.
 - **parent_composer_sort**: The sort name of the parent work composer.
 - **work_date**: The composition date of the work, or the first parent work
   that has a composition date. Format: yyyy-mm-dd.
-- **parentwork_workid_current**: The Musicbrainz id of the work as it was when
+- **parentwork_workid_current**: The MusicBrainz id of the work as it was when
   the parentwork was retrieved. This tag exists only for internal bookkeeping,
   to keep track of recordings whose works have changed.
