+# PlayerInfo mod for MineClone 2
+
+This is a helper mod for other mod to query the nodes around the player.
+
+Every half second the mod checks which node the player is standing on, which
+node is at foot and head level and stores inside a global table to be used by mods:
+
+- `mcl_playerinfo[name].node_stand`
+- `mcl_playerinfo[name].node_stand_below`
+- `mcl_playerinfo[name].node_foot`
+- `mcl_playerinfo[name].node_head`
