How to edit wiki pages (e.g. the user sights CDK)

Hey there

I was in the motions of editing one of my custom sights while cross-referencing the user sights CDK (User-made sighting reticles - War Thunder Wiki), and have discovered it to be somewhat lacking in some areas, as well as other basic edits. I am now trying to add content to this page to help others that may have similar issues as I had. However, I cannot for the life of me figure out how to edit pages on the wiki, and so cannot do this. Is this an issue on my end, or is there a way that I currently do not know about in order to edit a page?
