Vital articles is a list of subjects for which Wikipedia should have corresponding high-quality articles. It serves as a centralized watchlist to track the status of Wikipedia's most essential articles. This is one of the sub-lists of the fifty thousand article Vital articles/Level 5 and is currently under construction.

Articles are labelled as:

• Featured articles
• Former featured articles
• A-class articles
• Good articles
• Delisted good articles
• B-class articles
• C-class articles
• Start-class articles
• Stub-class articles
• List-class articles
• Unassessed
• A full list is at Template:Icon/doc

These symbols and article counts are updated daily by User:cewbot.

• The bot only update counter with the pattern "(000 articles)" in section title.
• All attributes of articles get from corresponding categories.
• The bot will automatically update the summary table if there are summary table marks. Please refer to Wikipedia:Vital articles for the example of summary table.
• Every time you modify main sections, please adjust User:Cewbot/log/20200122/configuration#Topics as well! This will avoid articles being listed in Category:All Wikipedia vital articles in an unknown topic.
