+This archive contains the DBSCAN Extension for NetLogo, release 0.2.1.
+
+To install the extension, copy the folder dbscan (not just the content) into NetLogo's app/extensions folder. 
+For NetLogo 6.1, consider using the Extension Manager as the recommended approach.
+
+For more information and detailed installation and usage instructions, refer to https://github.com/chrfrantz/NetLogo-Extension-DBSCAN#readme
