 ### Why
 
-Reusable util code
+Reusable Kyber utilities
 
 ### What
 
 - ctx.go: Context that ignores being cancelled
+- http.go: Resty HTTP client with easy configs
 - map.go: Collects values from a slice
 - num.go: Conversions, Min, Max, Abs
 - slice.go: Checks for existence, maps with fn, gets unique elements, filters
+- string.go: String utils
