+## How default inclusion rules are defined
+
+    OTHER_FOOTWAY_RULES = {'highway':['steps','living_street','pedestrian','track','path'],'foot':['yes','designated','permissive'],'footway': ['alley','path','yes']}
+
+This is described in the OSMNX standard, that you can check at the documentation, such as in [this function](https://osmnx.readthedocs.io/en/stable/user-reference.html#osmnx.features.features_from_address), basically tags are mapped as dicts and for having the union of many you just pass a list with the values.
+
+Then, in the same order:
+
+- [highway=steps](https://wiki.openstreetmap.org/wiki/Tag:highway=steps) : steps, stairs
+- [highway=living_street](https://wiki.openstreetmap.org/wiki/Tag:highway=living_street) : living streets, that are streets with explicit shared use
+- [highway=pedestrian](https://wiki.openstreetmap.org/wiki/Tag:highway=pedestrian) : explicit and exclusive pedestrian paths, generally in very urbanized areas
+- [highway=track](https://wiki.openstreetmap.org/wiki/Tag:highway=track) : tracks frequently allow pedestrians, being sometimes also the main pedestrian path in some less urbanized areas
+- [highway=path](https://wiki.openstreetmap.org/wiki/Tag:highway=path) : this one can be tricky, a good candidate for exclusion in some areas, since may be used for car roads (even tough they maybe be re-tagged with a better highway=* value)
+- [foot=yes](https://wiki.openstreetmap.org/wiki/Tag:foot=yes) : sometimes there's no pedestrian dedicated path, so the street is used for foot, in a sort of improvised way
+- [foot=designated](https://wiki.openstreetmap.org/wiki/Tag:foot=designated) : designated footways, this will include obviously sidewalks, so some will be later excluded, read the second part of this documentation
+- [foot=permissive](https://wiki.openstreetmap.org/wiki/Tag:foot=permissive) : even more "improvised" footways, can be in the sense that the permission might be removable
+- [footway=alley](https://wiki.openstreetmap.org/wiki/Tag:footway=alley) : one of less common footways, included because it's on the wiki
+- [footway=path](https://wiki.openstreetmap.org/wiki/Tag:footway=path) : one of less common footways, included because it's on the wiki
+- [footway=yes](https://wiki.openstreetmap.org/wiki/Tag:footway=yes) : one of less common footways, included because it's on the wiki
+
+## How default exclusion rules are defined
+
+    OTHER_FOOTWAY_EXCLUSION_RULES = {'highway': ['trunk','motorway','primary','trunk_link','motorway_link','primary_link']}
+
+Same standard as before. Since OSMNX will download all the features containing the tags in the other list, we must exclude some features with tags that are in a bigger hierarchical level.
+
+Then, in the same order:
+
+- [highway=trunk](https://wiki.openstreetmap.org/wiki/Tag:highway=trunk) : trunk roads, a pedestrian should never walk there
+- [highway=trunk_link](https://wiki.openstreetmap.org/wiki/Tag:highway=trunk_link) : same as trunk roads
+- [highway=primary](https://wiki.openstreetmap.org/wiki/Tag:highway=primary) : primary roads, generally a pedestrian shouldn't walk there
+- [highway=primary_link](https://wiki.openstreetmap.org/wiki/Tag:highway=primary_link) : same as primary roads
+- [highway=motorway](https://wiki.openstreetmap.org/wiki/Tag:highway=motorway) : motorways, a pedestrian should never walk there
+- [highway=motorway_link](https://wiki.openstreetmap.org/wiki/Tag:highway=motorway_link) : same as motorways roads
+
+Depending on the local standard, secondary and even tertiary roads might also be included on the list.
+Depending on the local standard, maybe for example primary roads might be cut off from the list.
