### ERROR: You must define a `{{ include.missing_block }}` field {: style="color:red" } The glossary template requires that you provide text that {{ include.purpose }}. To get rid of this message and take advantage of this template, define the `{{ include.missing_block }}` field for the `{{ include.term }}` glossary term and populate it with content. See `_data/glossary/_example.yml` for reference.
