First Time Video Editing, need help with rendering and one other

(MAY OR MAY NOT BE A REPOST, MY BROWSER CRASHED). Hey whoever is reading, I’m new to blender because I needed to create a video for a school project, I got the video all done, audio and editing and all, but I cannot figure out how to download/render/finish the video if you know what I mean. If someone could help, that would be great!
