{{hatnote|This template is for linking to main content. For the mainspace detection template, see [[:template:main other]].}}

When a {{Wikipedia|Wikipedia:What is an article?|Wikipedia article}} is large, it is often written in {{Wikipedia|Wikipedia:Summary style|summary style≈≈. This {{Wikipedia|Wikipedia:Template messages|template}} is used after the heading of the summary, to link to the subtopic article that has been summarized. For {{Wikipedia|Help:Category|Category namespace}}, please use '''{{tl|Cat main}}''' instead.

Use of this template should be restricted to the purposes described above. It is '''not''' to be used as a substitute for inline links or {{tl|Further}} template. The latter is used when the section expounds a specific aspect of the topic instead of summarizing its article. For example, in [[phthalate]], the template under the "Endocrine disruptor" section should '''not''' be {{tlf|Main|Endocrine disruptor}}, because the section specifically deals with phthalate as an endocrine disruptor and not endocrine disruptors in general.

This template should also not be used in lead sections. A lead section is always a summary of its own article, not any other; as such, the only appropriate target for a {{tl|Main}} link in the lead section would be the article itself, which is not useful. {{tl|Broader}} may be appropriate in this case.

==Usage==
<!--{{see|WP:SUMMARYHATNOTE}} This won't work with external links, so we'll fake it instead: -->
{{em|See: {{Wikipedia|WP:SUMMARYHATNOTE}}}}
{{startplainlist}}
* {{vad|Basic usage:|7.5em|left}} <code>{{((}}{{BASEPAGENAME}}{{!}}{{var|page}}{{))}}</code>
* {{vad|All parameters:|7.5em|left}} <code>{{((}}{{BASEPAGENAME}}{{!}}{{var|page1}}{{!}}{{var|page2}}{{!}}{{var|page3}}{{!}}&nbsp;...&nbsp;{{!}}l1&nbsp;{{=}}&nbsp;{{var|label1}}{{!}}l2&nbsp;{{=}}&nbsp;{{var|label2}}{{!}}l3&nbsp;{{=}}&nbsp;{{var|label3}}{{!}}&nbsp;...&nbsp;{{!}}selfref&nbsp;{{=}}&nbsp;{{var|yes}}{{))}}</code>
{{endplainlist}}

==Parameters=={{Wikipedia|Help:Colon trick|colon trick}}, and links to sections are automatically formatted as ''page § section'', rather than the MediaWiki default of ''page#section''.
*<code>l1</code>, <code>l2</code>, <code>l3</code>, ... ''or''<code>label 1</code>, <code>label 2</code>, <code>label 3</code>, ... – optional labels for each of the pages to link to (this is for articles where a piped link would be used). Note that the extra parameters use a lower case 'L', for example, <code>l1</code>, <u>not</u> <code>L1</code>.
*<code>selfref</code> – if set to "yes", "y", "true" or "1", adds the CSS class "selfref". This is used to denote self-references to Wikipedia. See [[Template:Selfref]] for more information. This is only necessary in articles and other content (e.g. templates) that will appear in articles, and need not be added for uses of this template on <code>Wikipedia:</code> namespace pages.

==Examples==
{{hatnote|Underscores (_) between words are not necessary}}
*<code><nowiki>{{Main}}</nowiki></code> &rarr; {{main|category=no}}
*<code><nowiki>{{Main|Article}}</nowiki></code> &rarr; {{main|Article}}

*<code><nowiki>{{Main|Article#Section|l1=Custom section label}}</nowiki></code> &rarr; {{main|Article#Section|l1=Custom section label}}

==Errors==
If the name of the first page that you want to link to is not specified, the current page name (with no namespace prefix) is used instead:
*{{Main|category=no}}

No errors can be displayed due to the illegal usage of parameters or other usages (i.e. the first parameter can be omitted, other parameters can be used even if the first one is empty (and automatically filled with the current page name (with no namespace prefix)), equals sign can be used as one of the parameters, and template can be used by direct call to the module (using "#invoke")). This is not the case for {{tl|see also}}, for example.
