+// Package jsoniter implements encoding and decoding of JSON as defined in
+// RFC 4627 and provides interfaces with identical syntax of standard lib encoding/json.
+// Converting from encoding/json to jsoniter is no more than replacing the package with jsoniter
+// and variable type declarations (if any).
+// jsoniter interfaces gives 100% compatibility with code using standard lib.
+//
+// "JSON and Go"
+// (https://golang.org/doc/articles/json_and_go.html)
+// gives a description of how Marshal/Unmarshal operate
+// between arbitrary or predefined json objects and bytes,
+// and it applies to jsoniter.Marshal/Unmarshal as well.
+//
+// Besides, jsoniter.Iterator provides a different set of interfaces
+// iterating given bytes/string/reader
+// and yielding parsed elements one by one.
+// This set of interfaces reads input as required and gives
+// better performance.
