+```
+
+### Configure blob storage in VM
+
+```
+vim ~/blob_fuse_connection.cfg
+accountName myaccount
+accountKey myaccesskey==
+containerName mycontainer
+```
+
+### Setup various filesystem dependencies / zones
+
+```
+mkdir /home/ubuntu/osmmapdata
+sudo chown: /home/ubuntu/osmmapdata
+sudo mkdir /mnt/resource/blobfusetmp
+sudo chown ubuntu: /mnt/resource/blobfusetmp
+```
+
+### Mount blob storage for use
+
+```
+blobfuse /home/ubuntu/osmmapdata \
+    --tmp-path=/mnt/resource/blobfusetmp \
+    --config-file=/home/ubuntu/blob_connection.cfg \
+    -o attr_timeout=240 \

+### Midwest USA
+
+```
+./process_maps.py --use-ram --max-heap-space 48g \
+    --output-map-name midwest \

+```
+
+### Central America
+
+*NOTE: This CAN NOT fit into 64Gb RAM, you'll need to setup a 128Gb SSD/Disk at ~/osm_map_processing/tmp for this to not enounter heap space errors*
