+// Package gojay implements encoding and decoding of JSON as defined in RFC 7159.
+// The mapping between JSON and Go values is described
+// in the documentation for the Marshal and Unmarshal functions.
+//
+// It aims at performance and usability by relying on simple interfaces
+// to decode and encode structures, slices, arrays and even channels.
+//
+// On top of the simple interfaces to implement, gojay provides lots of helpers to decode and encode
+// multiple of different types natively such as bit.Int, sql.NullString or time.Time
