+# Pathfinder Tester
+
+Usage:
+
+Use the Pathfinder Tester tool (`testpathfinder:testpathfinder`).
+Here's how it works:
+
+* Place on node: Set destination position
+* Punch: Find path
+* Sneak+punch: Select pathfinding algorithm
+
+Information will be shown in chat. If a path was found, all waypoints
+will be shown for a few seconds.
+
+See `init.lua` for config variables.
