Bản mẫu:Update-after/doc

== Usage**
(all parameters are optional)- Parameters 1, 2, and 3 are respectively the year, month, and day that the template should activate. If the day is omitted, the template will activate on the first day of the specified month. If the month is also omitted, the template will activate on 1 January of the specified year. If the year is also omitted, the template will activate immediately. One should try to specify month and year.  If parameters 1, 2, and 3 are left blank, a bot will add it later.- Parameter 4 is a custom category, such as a WikiProject's article maintenance category. The article will be placed in the specified category when the template is activated (but only if the template is used in an article in the main namespace, not if it is used on a talk page or in any other non-main namespace). The category name must be specified without square brackets and without the "Category:" prefix. In addition to any category specified here, articles are automatically placed in :Category:Wikipedia articles in need of updating or one of its dated subcategories, when the date is specified. To use this parameter even when the first three parameters are omitted, you can write 4.
** Examples: Specifying |4=United States articles in need of updating places the article in :Category:United States articles in need of updating as well as :Category:Wikipedia articles in need of updating. Note: at present this parameter is not being used on Wikipedia. - Named parameter reason is used to leave a note for future editors about what exactly needs to be changed or where to find the new information. it has no effect on the template itself.
Please read Wikipedia:Avoid statements that will date quickly; use Update after only in exceptional cases. Do not use this template on pages which simply need to be reviewed later to see if they might need updating; it should only be used when there is a certainty or very high probability that an update is needed.  Do not use this template on talk pages; it is intended for inline usage, like Citation needed. It is probably not necessary to use this template on frequently edited articles such as for current events, as they will be being updated on a regular basis. Do not use this template within section heading (i.e., between the opening and closing  of a section heading), as it will break the heading.
