This is the

{{tl2}} template.

{{tl2}} is similar to
{{tl}}. Tl stands for Template link.

{{tl2}} is a macro template used to display a template name as a link surrounded by braces, thus showing how the template name would be used in code. Its primary use is in instruction and documentation.

{{tl2}} differs from
{{tl}} in that it displays with a wider, monospaced text style (like

{{tlx}}) and also takes the named parameters |sister= and |lang= so that it may also be used to list and link templates on other English and non-English-language sister projects.

{{tlx}} displays with the same enhanced presentation and can also expand several placeholder parameters to generate a sample template call.
