Editing Template:Citation Style documentation/registration (section)

=====Tracking of free DOIs=====
* The template is able to recognize known free-to-read [[DOI registrant]]s, based on a list in [[Module:Citation/CS1/Configuration]]. Once a free registrant is identified, the <code>10.xxxx/...</code> part of the DOI associated with the registrant can be added to the list under ''local function build_free_doi_registrants_table()''. If {{para|doi-access|free}} is not set, it will place the page in [[:Category:CS1 maint: unflagged free DOI]], which is routinely cleared by [[User:Citation bot]]. 
* The template is also able to recognize known free-to-read journals, assuming they have a clear <code>10.xxxx/yyyy....</code> DOI pattern. Once that pattern is identified, it can be added to [[Module:Citation/CS1/Configuration]] under ''local extended_registrants_t = {'' with the format <code>['XXXX'] = {'YYYY'},</code>. If there are multiple journals with the same DOI prefix, they can be grouped together with the format <code>['XXXX'] = {'YYYY', 'ZZZZ', '...'},</code>.
* If you add a free registrant/free journal to the lists in [[Module:Citation/CS1/Configuration]], leave a note at [[User talk:Citation bot]] so the bot knows about it.
