 ##JSON Dataset
 
 JSON dataset work is based upon the many efforts of Mosh (@nyxbone) and @cyb3rops who manage Ransomware Summary public spreadsheet that is co-hosted in this repository. Spreadsheet data remains the intellectual property of Mosh and is taken 'as-is' and processed into a JSON output to allow its use in various shell or programming operations.
+
+###Updating the dataset
+To update the dataset first clone this repository and then run 'python ./UpdateJsonDataset/update_json.py'
+
+The latest version of the Ransomware Summary spreadsheet will then be downloaded and processed into a local json output which will be found in the core folder of your local repository. To change the source and destinations for local files edit the constants found in the header of the 'update_json.py' file.
