 Ever ran into a cheater, looked at their profile, and realized all their friends are cheaters too? I have, and this tool is a way to measure degrees of separation from a specific individual
 
 Steam Relationships querries the Steam WebAPI to get public friends lists, and then recursively search those friend lists as well. This process repeats until a certain number of "degrees" have been met (a set recursion level specified by the user). The results of these querries are put in a database that can then be shared and used for other purposes
+
+## REQUIREMENTS
+
+1. A [Steam DevAPI key](https://steamcommunity.com/dev/apikey)
