 ##### Credits
 The parameter names wordlist is created by extracting top parameter names from [CommonCrawl](http://commoncrawl.org) dataset and merging best words from [SecLists](https://github.com/danielmiessler/SecLists) and [param-miner](https://github.com/PortSwigger/param-miner) wordlists into that.
+`special.json` wordlist is taken from [data-payloads](https://github.com/yehgdotnet/data-payloads).
