+
+NOTE: I had some user confusion. It seems to be best to create the user that this server will run as and use that account to do all the setup and for the database user. It wanted the data and src directories to be under that user's home directory.
+
+Locations of certain relevant things in the server
+
+    Tile Directories:           /var/lib/mod_tile
+    Renderd Config:             /usr/loocal/etc/renderd.conf
+    Mapnik XML Files:           /home/{renderer user}/src/openstreetmap-carto/*.xml
+
+carto project.mml > mapnik.xml
+
+    Got a bunch of warnings like the following...
+
+    Warning: amenity-points.mss:2328:6 Styles do not match layer selector .text-low-zoom.
+
+
+"Loading Data" 
+
+    Specified North America instead of Azerbaijan from Download site: http://download.geofabrik.de/index.html
+
+    wget http://download.geofabrik.de/north-america-latest.osm.pbf
+
+    A better initial test might be just Michigan - be sure to change to that when using osm2pgsql
+
+    http://download.geofabrik.de/north-america/us/michigan-latest.osm.pbf
+
+
+
+To run osm2pgsql I had to create myself as a postgres superuser then use the following command to point to the North American data.
+
+    osm2pgsql -d gis --create --slim  -G --hstore --tag-transform-script ~/src/openstreetmap-carto/openstreetmap-carto.lua -C 2500 --number-processes 1 -S ~/src/openstreetmap-carto/openstreetmap-carto.style ~/data/north-america-latest.osm.pbf
+
+    Note: "-C" is the amount of memory in MB, change "--number-processes" to the available CPUs.
