 library, hence the name.
 
-## Design goals
-
-The main goal of this validator is to produce *human-comprehensible* error
-messages if a JSON-document/instance does not comply to its schema.
-
-By default this is done with exceptions thrown at the users with a helpful
-message telling what's wrong with the document while validating.
-
-Starting with **2.0.0** the user can pass a `json_schema::basic_error_handler`-derived
-object along with the instance to validate to receive a callback each time
-a validation error occurs and decide what to do (throwing, counting, collecting).
-
-Another goal was to use Niels Lohmann's JSON-library. This is why the validator
-lives in his namespace.
-
-## Thread-safety
-
-Instance validation is thread-safe and the same validator-object can be used by
-different threads:
-
-The validate method is `const` which indicates the object is not modified when
-being called:
-
-```C++
-	json json_validator::validate(const json &) const;
-```
-
-Validator-object creation however is not thread-safe. A validator has to be
-created in one (main?) thread once.
-
-## Weaknesses
-
-Numerical validation uses nlohmann-json's integer, unsigned and floating point
-types, depending on if the schema type is "integer" or "number". Bignum
-(i.e. arbitrary precision and range) is not supported at this time.
