+
+Package validator implements value validations for structs and individual fields based on tags.
+
+It has the following **unique** features:
+
+- Cross Field and Cross Struct validations by using validation tags or custom validators.
+- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
+- Ability to dive into both map keys and values for validation
+- Handles type interface by determining it's underlying type prior to validation.
+- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
+- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
+- Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError
+- Customizable i18n aware error messages.
+- Default validator for the [gin](https://github.com/gin-gonic/gin) web framework; upgrading from v8 to v9 in gin see [here](https://github.com/go-playground/validator/tree/master/_examples/gin-upgrading-overriding)
+
+Installation
+------------
+
+Use go get.
+
+ go get github.com/go-playground/validator
+
+Then import the validator package into your own code.
+
+ import "github.com/go-playground/validator"
+
+Error Return Value
+-------
+
+Validation functions return type error
+
+They return type error to avoid the issue discussed in the following, where err is always != nil:
+
+* http://stackoverflow.com/a/29138676/3158232
+* https://github.com/go-playground/validator/issues/134
+
+Validator returns only InvalidValidationError for bad validation input, nil or ValidationErrors as type error; so, in your code all you need to do is check if the error returned is not nil, and if it's not check if error is InvalidValidationError ( if necessary, most of the time it isn't ) type cast it to type ValidationErrors like so:
+
+```go
+err := validate.Struct(mystruct)
+validationErrors := err.(validator.ValidationErrors)
+ ```
+
+Usage and documentation
+------
+
+Please see https://pkg.go.dev/github.com/go-playground/validator/v10 for detailed usage docs.
