got a time i wanna submit

I would imagine you would need to have it recorded and submit it via Twitch or Youtube.

Did you stream it or record it?

Your run must either be a video on Youtube, or something permanent on Twitch. You can then submit by selecting the category in the leaderboards tab, and clicking the 'submit' run button where you can fill out all the relevant information. If unsure about something then leave them blank, and they'll be filled in by one of the mods when reviewing. Hope this helps
