 ### Parallelization
 
-FastANI (v1.1 onwards) supports multi-threading, see the help page on how to configure thread count. To parallelize FastANI beyond single compute node, users also have the choice to simply divide their reference database into multiple chunks, and execute them as parallel processes. We provide a [script](scripts) in the repository to randomly split the database for this purpose.
