How to contribute in GDevelop Wiki

In the wiki guides and tutorials , I am finding some outdated content on GDevelop Wiki which needs to be modified as new versions coming in.
But when I visit the source code it shows me this message :
“This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong.”
How can I edit or propose edits to these pages ?

Some pages can never be modified by non-confirmed users, as they are sensitive, and sometimes when trolls come flooding fake edits all pages are blocked from editing. If you want to propose changes on a blocked page, try contacting a confirmed user or admin (4ian, bouh, etc) with those changes.
