How to place markers on the map?

Question

Google Maps

There is a site , I wanted to make the same block with a map on the site and arrange my branches, when clicked on, a pop-up did not pop up, but information simply popped up.
Somewhere on the Internet I saw a guide, I can not find it. Pictures of the label so that you can fill in your own.

Answer 1

The universal version would look like this:
1. Put json with branches on the site. There is also an icon.
2. Upload the file, place the markers.
3. We describe the handler of the marker, what to do there, float, fly out, jump out.
