Look for a series of templates, with the 'Add new entries' hidden comment, and place your entry there:
<!-- Add new entries to the TOP of the following list --> {{subst:afd3 |pg=NominationName}} <!-- YOUR ENTRY HERE --> {{Wikipedia:Articles for deletion/Underground basket-weaving}} {{Wikipedia:Articles for deletion/History of Outer Slobovia}} {{Wikipedia:Articles for deletion/Bar coaster flipping}}
use edit summary: Listing [[Wikipedia:Articles for deletion/NominationName]], and save the page.
Notify users and WikiProjects:
notify creator[f] and main editors[g] by adding {{subst:Adw|ArticleName|NominationName}} to their user Talk page
This lets log viewers know what projects were notified, and prevents duplicate effort.
Notes
^ArticleName: anyplace you see italics in the instructions, you need to substitute the appropriate text. For example, if you want to delete the article "Underground basket-weaving", then wherever you see ArticleName you should instead substitute "Underground basket-weaving".
^Nomination name: The first time a page is nominated for deletion, the NominationName is the same as ArticleName. After that, it takes on a parenthetical suffix to disambiguate it from previous nominations. The second time an article is nominated, it may be called, for example, "Underground basket-weaving (2nd nomination)".
^Substitute the article name you're nominating for deletion. If this article was nominated for deletion before, then use, "ArticleName (2nd nomination)" instead, "ArticleName (3rd nomination)" and so on; here, and everywhere else where NominationName appears in the instructions.
^Deletion logs have the filename format [[Wikipedia:Articles for deletion/Log/yyyy Month dd]]. The day is not zero-padded; so the log filename on New Year's Day ends "January 1" (not, "January 01").
^You may wish to refresh the page, to ensure you are pointing to the correct log.
^The page creator can be found by examining the page History, and clicking the 'oldest' link at the top of the page.
^The main editors of the page can be found by going to the History tab, and clicking Page Statistics at the top of the page; then 'Top editors'.
^Which WikiProjects should you notify? The ones listed (usually) at the top of the Talk page of the article.
^The deletion log has today's date on it, and rolls over to the next day at midnight UTC; be sure to use the same log as you did before.
