How to mark an answer as a solution?

I posted a question and got an answer. How can I mark it as a solution? I couldn’t find any buttons to click.

Is it so only in Help category? Or is it still not implemented?

Hmm, I don’t have this button !(

Seems that I also cannot embed images with markdown.

I dont have that button. so I had to edit headline and wrote [solved].

ability for all to change headlines is not a good idea. I dont remember this feature on any other serious documenting site(edit: apparently I’m wrong. thank you @sandino.) sooner or later it ll be a problem.

Look at Stackoverflow, it allows changing title. Although at SO you can see changes history.

you are right. I took that part back.
