+Subject: [PATCH] Paper Metrics
+
+Removes Spigot's mcstats metrics in favor of a system using bStats
+
+To disable for privacy or other reasons go to the bStats folder in your plugins folder
+and edit the config.yml file present there.
+
+Please keep in mind the data collected is anonymous and collection should have no
+tangible effect on server performance. The data is used to allow the authors of
+PaperMC to track version and platform usage so that we can make better management
+decisions on behalf of the project.
