Articles created without a category should be tagged with a maintenance tag. Use the {{Uncategorized}} tag to put articles in a maintenance category. Optionally add a date parameter like {{Uncategorized|date=August 2026}} to put articles in by-date maintenance categories.
Such tagged articles are found at Uncategorized pages. You can try to categorize articles yourself. One useful technique is to follow links in the article to other similar articles and see how they are categorized, so you know what to copy.
The lead section is an essential
summary of an article, located above the first heading.
In the source text (the text in the edit window), a heading looks like this:
== This is a heading ==
The lead section is a very important part of every article. The length should correspond to the overall length of the article: an article of 50,000 characters might well have a three paragraph lead, while one of 15,000 or less should limit itself to one or two paragraphs. The text should give a good overview of the article, but it should also get the reader hooked and interested in learning more. Take a look at some featured articles for inspiration.
It is often a good idea to align a representative image with the lead by placing [[File:Filename.jpg|thumb|caption]] just before the first heading. (Filename is the name of the desired file and caption is a description of the image).
