The Help namespace is a namespace consisting of Wikipedia pages whose titles begin with the prefix Help:, such as Help:Link.

These pages contain information intended to help use Wikipedia or its software. Some of these pages are intended for readers of the encyclopedia; others are intended for editors, whether beginning or advanced. Some of the pages in the Help namespace are copied from Meta-Wiki.

There is a large amount of overlap between the Help namespace and the Project namespace (pages with the Wikipedia: prefix). For this reason redirects and hatnotes are often set up between these two namespaces. pt:Wikipédia:Domínio de ajuda
