Alternatively, you can install the extension using the Extension Manager provided from NetLogo 6.1 onwards (see Variant 1). For older versions of NetLogo (i.e., 6.0 or lower) you can download the corresponding jar files directly (Variant 2). Alternatively, for all supported versions of NetLogo you can build the extension from source (Variant 3).

 In addition, you will need to build the [DBSCAN repository](https://github.com/chrfrantz/DBSCAN.git) (Command: `mvn package`) which contains the underlying DBSCAN algorithm. Place both jar files in the extensions subfolder `dbscan` (following the structure described under Variant 2). Note that all builds have been primarily tested using Java 11.
