In the CESBA Wiki, references are usually indicated by external links. Usually, you add a heading "References" below your article:
Beyond this heading, you can add the references you used for the article.
References that refer to other websites or documents that are accessible online
Use external links for html pages, pdf documents etc. that are available online and add the year your link was last updated in brackets.
An external link is expressed by single square brackets
Add a blank character after the URL before the square bracket, write the title of the article/the name of the homepage/document etc. and add the year of release/last update in brackets:
[http://www.alpine-space.eu Homepage of Alpine Space programme (2014)]
Safe your edits and see if your links work.
