{{About}} is a commonly used hatnote template on Wikipedia, and should be placed at the top of an article (but following {{Short description}}, if present), linking the reader to other articles with similar titles or concepts that they may have been seeking instead. The template has several formats, including:
{{About}}→ Lua error in Module:Hatnote_list at line 170: attempt to call field '_formatLink' (a nil value).{{About|Use1}}→ Lua error in Module:Hatnote_list at line 170: attempt to call field '_formatLink' (a nil value).{{About||Use2|Article2}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1||Article2}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1||Article2|and|Article3}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|and|Article3}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|and|Article3|and|Article4|and|Article5}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|Use3|Article3}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|other uses}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).
Alternately, a section=yes parameter can be added to the {{About}} template for use at the top of a section. When using this parameter, the wording in the template changes to specify that it is being used in a section:
{{About|Use1|section=yes}}→ Lua error in Module:Hatnote_list at line 170: attempt to call field '_formatLink' (a nil value).{{About|Use1||Article2|section=yes}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|section=yes}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|and|Article3|section=yes}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).{{About|Use1|Use2|Article2|other uses|section=yes}}→ Lua error in Module:Hatnote_list at line 44: attempt to call field 'formatPages' (a nil value).
A |text= option adds text to the end; this should only be used when truly necessary, when the other hatnote templates listed below don't suffice.
The |selfref=yes option marks the entire hatnote as a Wikipedia self-reference, causing it to be omitted when the page content is reused outside of Wikipedia (see {{self reference}} and MOS:SELFREF for more details).
For more options, find "{{About}}" in the text below.
