 This script will update any of the Country Code, Country, State, City and Location data that is missing in sidecard files. If a Lightroom DB is set, it will read any data from the database and fill in the fields before it tries to get the location name from google with the Latitude and Longitude found in either the XMP sidecar file or the LR database.
 
-This script used the [Python XMP Tool kit](http://python-xmp-toolkit.readthedocs.io/)
+#### Installing and setting up
+
+The script uses the following external non defauly python libraries
+* xmp toolkit
+* requests
+
+install both with the pip3 command
+```
+pip3 install requests
+pip3 install python-xmp-toolkit
+```
+
+XMP Toolkit also needs the [Exempi Library](http://libopenraw.freedesktop.org/wiki/Exempi). This one can be install via brew or macports directly.
+See more information for [Python XMP Tool kit](http://python-xmp-toolkit.readthedocs.io/)
+
+The scripts python3 enviroment path (#!...) needs to be set so it points to a valid python3 install.
