+# pathetic - a shitty path block enhancement mod
+
+does fun things with path blocks!! most likely not the first person to do these things, but it seems like a fun way to
+get into modding.
+
+## current goals
+
+* automatically convert often walked over grass/dirt blocks into path blocks
+    * current plan is at least 5 times walked across in recent x amount of ticks, debounced by x ticks
+* automatically converted paths fade back out over time as they become "overgrown"
+
+## current status
+
+* very basic MVP implementation as a mixin, with cursed in memory state handling
+    * blocks that have been walked over 5 times, within any overall timeframe are converted, and tagged as created by
+      the mod
