-Core part of `purescript-argonaut` that contains basic types for `Json`, case analysis, printer and parser.
+[Argonaut](https://github.com/purescript-contrib/purescript-argonaut) is a collection of libraries for working with JSON in PureScript. `argonaut-core` defines the core `Json` type, along with basic parsing, printing, and folding functions which operate on it.

+- [purescript-argonaut-codecs](https://github.com/purescript-contrib/purescript-argonaut-codecs) provides codecs based on `EncodeJson` and `DecodeJson` type classes, along with instances for common data types and combinators for encoding and decoding `Json` values.
+- [purescript-codec-argonaut](https://github.com/garyb/purescript-codec-argonaut) supports an alternative approach for codecs, which are based on profunctors instead of type classes.
+- [purescript-argonaut-traversals](https://github.com/purescript-contrib/purescript-argonaut-traversals) defines prisms, traversals, and zippers for the `Json` type.
+- [purescript-argonaut-generic](https://github.com/purescript-contrib/purescript-argonaut-generic) supports generic encoding and decoding for any type with a `Generic` instance.
