The first step to creating a map is to open the project with the data that you want to show in your map. Once in the project dashboard, you can find the Maps button on the left hand side.
Once in the Maps Dashboard, you can see all of your existing maps in the project and create a new map. To create a new map, click the "New Map" button in the upper right.
You will need to select some basic defaults for the map. First give it a name and optional description.
After you've given it a name and description, you can select the baselayers that you want in the map. The default one will be the one shown. and you must have at least one.
After you have selected the base layers, you can select the other layers that you'd like to add to the map.
Now that you have done that, your map is created. Your layers have been added. The next steps are to order the layers, render them the way you want them to be styled, and add optional items like popups, geocoding search, or adding new layers.
