Making a Nexus Map

Hi!

I am building a Nexus map, but to complete it, I need to know some things...
How can I add weapon on the map? Like shops..
How can I add texts on the map?
How to add texts to bulletin, signs and stuff?

I'm only using editor. Do I need to use anything else?
Here's a pic of the map till now..
