 ## New Instructions
 
+* NOTE: when downloading OSM data towards the end via JOSM, copy-paste the output of the download script but add `(._;>;);out;` to the end instead of `out geom;` so JOSM picks it up.
+* NOTE: also add `way["highway"="construction"](area.searchArea);way["highway"="path"](area.searchArea);way["highway"="cycleway"](area.searchArea);` to the end so that roads under construction and cartpaths show up in JOSM to be analyzed/replaced/modified/etc.
