+Do whatever you want with this software; I won't sue you over it. For the sake 
+of my own curiority I'd appreciate it if you let me know what you end up doing 
+with it, and it would be nice if to get a little acknowledgement, but don't feel
+obliged to do either. My views on copyright, copyleft and the ‘public domain’ 
+can be read in far more detail (here)[https://bengoldsworthy.net/2018/03/copywrong/].
+
+However, I am aware of the unfortunate fact that some people may be in a 
+situation that requires an ‘proper’ license, replete with legalese and capital 
+letters. For those people, the text of the Unlicense is reproduced below and 
+should be considered the ‘official’ license under which this software is 
+released.
+
+Wherever a license is specified for anything incorporated into this software 
+(e.g. code snippets, images, etc.), please respect what the license requests 
+that you do and don't do with it. It stops you getting sued, which is nice, but 
+it's also just polite.
