-# Charged URI and URI Charge
+# ChURI
+
+ChURI is a polyglot serializer, deserializer and validator supporting various data formats.
+
+The data processing is based on data schemas. Schemas are written in TypeScript. ChURI compiles such schemas into
+efficient code implementing serializers, deserializers, and validators for the data conforming to those schemas.
+
+The main data format supported is URI Charge Notation, which is used to encode data included into URI. Such URI
+is called Charged URI, or ChURI.
+
+Other data formats supported out of the box:
+
+- JSON
+- `application/x-www-form-urlencoded` (URI query parameters)
+- URL-encoded
+- plain text
+
+Some formats support _insets_ containing data in another formats. For example, the `application/x-www-form-urlencoded`
+format allows query parameter values to be encoded as URL-encoded ones, as plain text, or as URI Charge. The choice
+is made by data schema.
