The new Wiki on UnrealEngine doesn’t give a user any ability to create a new page. Searching for something simply brings up the regular documentation search, so it’s not possible to actually create a page anymore.
I wanna add le tutorials 
For now you have to do it like that 
There are three standard ways to create a page on Mediawiki:
- Create a link to the page you want to create and then click the link
- Type in the URL to the page you want to create
- Search for the page you want to create
We removed the wiki-only search box to avoid confusion with the new unified header search, so you are currently left with just the first two options. We plan to improve the workflow in the future by simply adding a button to create a page. This seems better than the awkward ‘search for the page’ workflow anyway.
For more info on creating wiki pages, see the official Mediawiki page over it:

That would definitely be useful, both are pretty cumbersome 
Can’t seem to upload any images at the moment either.
Can’t figure out where the button is (in the Navigation drop down menu) or can’t upload them?
You can edit your username’s Talk page to create pages and to upload files and other stuff. Just Edit yout talk page and write stuff there. You can use your Talk page as a scratch pad to test out any wikitext feature you wanna learn/test out.
