# Installing the add-on
Extract the transparentmaps.zip file you received to your local PC and upload the transparentmaps folder contained within to your Open-Realty /addons directory. You should wind-up with something like:
/addons/transparentmaps
WARNING
Do NOT rename the folder, it must remain named 'transparentmaps' exactly.
TIP
Upload the files in binary format, and not ascii, otherwise your Open-Realty admin page may no longer display.
# Latitude & Longitude Fields
The installer automatically checks Open-Realty for fields that are Type: Latitude and Longitude. If you want to use pre-existing listing fields for your latitude and longitude data they must be configured as Field Type: Latitude and Longitude respectively via OR's Listing Field Editor.
The installer will create its own Latitude and Longitude fields if it does not locate any suitable fields. If you want to change the fields that are being used you must set any new fields as Latitude and Longitude field Types and delete any duplicate fields set to the same type so that only one Latitude and one Longitude field exists in your Listing Field Editor
TIP
You MUST have both a Latitude and Longitude listing field setup in Open-Realty, and your listings must contain valid Latitude and Longitude values in order for TransparentMaps to function properly.
