 # Genesis
 
-Typesafe generic functions for Go: filter, map, reduce, min, find etc.
+Myssed generic stdlib for slices and channels.
+
+**Some functions:**
+
++ Filter, Map, Reduce.
++ Min, Max, Sum.
++ Permutations, Product.
++ Any, All.
++ Contains, Find.
++ Shuffle, Sort.
++ Range, Count, Cycle.
+
+And much more.
+
+**Features:**
+
++ Typesafe.
++ Sync and async versions.
++ For slices and channels.
++ Pre-generated for all built-in types.

+## Examples
+
+Find minimal value in a slice of ints:
+
+```go
+s := []int{42, 7, 13}
+min = genesis.SliceInt{s}.Min()
+```
+
+Double values in a slice of ints:
+
+```go
+s := []int{4, 8, 15, 16, 23, 42}
+double := func(el int) int { return el * 2 }
+doubled = genesis.SliceInt{s}.Map(double)
+```
