 You can add attributes to your types to customize Schemars's derived `JsonSchema` implementation.
 
-Serde also allows setting `#[serde(...)]` attributes which change how types are serialized, and Schemars will generally respect these attributes to ensure that generated schemas will match how the type is serialized by serde_json. `#[serde(...)]` attributes can be overriden using `#[schemars(...)]` attributes, which behave identically (e.g. `#[schemars(rename_all = "camelCase")]`). You may find this useful if you want to change the generated schema without affecting Serde's behaviour, or if you're just not using Serde.

+## Supported Validator Attributes
+
+*These attributes will be processed in Schemars v0.8.4*
+
+<div class="indented">
+
+<h3 id="email-phone-url">
+
+`#[validate(email)]` / `#[schemars(email)]`<br />
+`#[validate(phone)]` / `#[schemars(phone)]`<br />
+`#[validate(url)]` / `#[schemars(url)]`
+</h3>
+
+Sets the schema's `format` to `email`/`phone`/`uri`, as appropriate. Only one of these attributes may be present on a single field.
+
+Validator docs: [email](https://github.com/Keats/validator#email) / [phone](https://github.com/Keats/validator#phone) / [url](https://github.com/Keats/validator#url)
+
+<h3 id="length">
+
+`#[validate(length(min = 1, max = 10))]` / `#[schemars(length(min = 1, max = 10))]`<br />
+`#[validate(length(equal = 10))]` / `#[schemars(length(equal = 10))]`
+</h3>
+
+Sets the `minLength`/`maxLength` properties for string schemas, or the `minItems`/`maxItems` properties for array schemas.
+
+Validator docs: [length](https://github.com/Keats/validator#length)
+
+<h3 id="range">
+
+`#[validate(range(min = 1, max = 10))]` / `#[schemars(range(min = 1, max = 10))]`
+</h3>
+
+Sets the `minimum`/`maximum` properties for number schemas.
+
+Validator docs: [range](https://github.com/Keats/validator#range)
+
+<h3 id="regex">
+
+`#[validate(regex = "path::to::regex")]` / `#[schemars(regex = "path::to::regex")]`
+`#[schemars(regex(pattern = r"^\d+$"))]`
+</h3>
+
+Sets the `pattern` property for string schemas. The `path::to::regex` will typically refer to a [`Regex`](https://docs.rs/regex/*/regex/struct.Regex.html) instance, but Schemars allows it to be any value with a `to_string()` method.
+
+Providing an inline regex pattern using `regex(pattern = ...)` is a Schemars extension, and not currently supported by the Validator crate. When using this form, you may want to use a `r"raw string literal"` so that `\\` characters in the regex pattern are not interpreted as escape sequences in the string.
+
+Validator docs: [regex](https://github.com/Keats/validator#regex)
+
+<h3 id="contains">
+
+`#[validate(contains = "string")]` / `#[schemars(contains = "string")]`
+</h3>
+
+For string schemas, sets the `pattern` property to the given value, with any regex special characters escaped. For object schemas (e.g. when the attribute is set on a HashMap field), includes the value in the `required` property, indicating that the map must contain it as a key.
+
+Validator docs: [contains](https://github.com/Keats/validator#contains)
+
+<h3 id="required">
+
+`#[validate(required)]` / `#[schemars(required)]`
+`#[validate(required_nested)]`
+</h3>
+
+When set on an `Option<T>` field, this will create a schemas as though the field were a `T`.
