+The Yojson library provides runtime functions for reading and writing JSON
+data from OCaml. It addresses a few shortcomings of its predecessor
+json-wheel and is about twice as fast (2.7x reading, 1.3x writing; results
+may vary).
+The design goals of Yojson are the following:
+- Reducing inter-package dependencies by the use of polymorphic
+variants for the JSON tree type.
+- Allowing type-aware serializers/deserializers
+to read and write directly without going through a generic JSON tree,
+for efficiency purposes.
+Readers and writers of all JSON syntaxic elements are provided
+but are undocumented and meant to be used by generated OCaml code.
+- Distinguishing between ints and floats.
+- Providing optional extensions of the JSON syntax.
+These extensions include comments, arbitrary strings,
+optional quotes around field names, tuples and variants.
+
+See {{:<http://json.org> JSON specification}json specification}.

+   The Yojson library provides several types for representing JSON values, with different use cases.
+
+   - The {{!basic}Basic} JSON type,
+   - The {{!safe}Safe} JSON type, a superset of JSON with safer support for integers,
+   - The {{!raw}Raw} JSON type, a superset of JSON, safer but less integrated with ocaml types.
+
+Each of these different types have their own module.
