Many of the most used templates on Commons do not have documentation pages that meet current community standards. The task is to find an document such pages:
1) **Finding** templates in need of documentation can be done with http://quarry.wmflabs.org/query/6313 query (also copied to [[https://commons.wikimedia.org/wiki/User:Jarekt/e|this page]] ).
2) **Documenting** templates should follow best Commons practices and should include: using /doc subpage and [[https://commons.wikimedia.org/wiki/Template:TemplateBox|Template:TemplateBox]] . All the categories should be at the /doc page and all the interwiki links should be done through wikidata. If edits need to be done to protected templates than a message should be left at the template talk page with [[https://commons.wikimedia.org/wiki/Template:Edit_request|Template:Edit_request]]. Documentation should include description of all the input parameters and might require studying the template code and the code of pages using it.
Recommended steps:
1. Create Wikipedia account if you do not have one.
2. Go to [this page](https://commons.wikimedia.org/wiki/User:Jarekt/e) and pick a template you would like to work on.
3. In most cases templates will only have "<noinclude>{{documentation}}</noinclude>" at the end that links to documentation which link to /doc subpage.
* If /doc subpage does not exist copy existing documentation somewhere and replace it with "<noinclude>{{documentation}}</noinclude>", then click on the red link to the /doc page. Once there use a link on the top to preload a TemplateBox with enough parameters and them merge old documentation into the page and expand it.
* If /doc subpage does exist but does not use TemplateBox, than add and fill the template. Preload pages [here](https://commons.wikimedia.org/wiki/Template:TemplateBox/doc#See_also) might be useful.
