+## Fluent Schema
+
+The [Validation and
+Serialization](../Reference/Validation-and-Serialization.md) documentation
+outlines all parameters accepted by Fastify to set up JSON Schema Validation to
+validate the input, and JSON Schema Serialization to optimize the output.
+
+[`fluent-json-schema`](https://github.com/fastify/fluent-json-schema) can be
+used to simplify this task while allowing the reuse of constants.
+
+### Basic settings
+
+```js
+const S = require('fluent-json-schema')
+
+// You can have an object like this, or query a DB to get the values
+const MY_KEYS = {
+  KEY1: 'ONE',
+  KEY2: 'TWO'
+}
+
+const bodyJsonSchema = S.object()
+  .prop('someKey', S.string())
+  .prop('someOtherKey', S.number())
+  .prop('requiredKey', S.array().maxItems(3).items(S.integer()).required())
+  .prop('nullableKey', S.mixed([S.TYPES.NUMBER, S.TYPES.NULL]))
+  .prop('multipleTypesKey', S.mixed([S.TYPES.BOOLEAN, S.TYPES.NUMBER]))
+  .prop('multipleRestrictedTypesKey', S.oneOf([S.string().maxLength(5), S.number().minimum(10)]))
+  .prop('enumKey', S.enum(Object.values(MY_KEYS)))
+  .prop('notTypeKey', S.not(S.array()))
+
+const queryStringJsonSchema = S.object()
+  .prop('name', S.string())
+  .prop('excitement', S.integer())
+
+const paramsJsonSchema = S.object()
+  .prop('par1', S.string())
+  .prop('par2', S.integer())
+
+const headersJsonSchema = S.object()
+  .prop('x-foo', S.string().required())
+
+// Note that there is no need to call `.valueOf()`!
+const schema = {
+  body: bodyJsonSchema,
+  querystring: queryStringJsonSchema, // (or) query: queryStringJsonSchema
+  params: paramsJsonSchema,
+  headers: headersJsonSchema
+}
+
+fastify.post('/the/url', { schema }, handler)
+```
+
+### Reuse
+
+With `fluent-json-schema`, you can manipulate your schemas more easily and
+programmatically and then reuse them thanks to the `addSchema()` method. You can
+refer to the schema in two different manners that are detailed in the
+[Validation and
+Serialization](../Reference/Validation-and-Serialization.md#adding-a-shared-schema)
+documentation.
+
+Here are some usage examples:
+
+**`$ref-way`**: refer to an external schema.
+
+```js
+const addressSchema = S.object()
+  .id('#address')
+  .prop('line1').required()
+  .prop('line2')
+  .prop('country').required()
+  .prop('city').required()
+  .prop('zipcode').required()
+
+const commonSchemas = S.object()
+  .id('https://fastify/demo')
+  .definition('addressSchema', addressSchema)
+  .definition('otherSchema', otherSchema) // You can add any schemas you need
+
+fastify.addSchema(commonSchemas)
+
+const bodyJsonSchema = S.object()
+  .prop('residence', S.ref('https://fastify/demo#address')).required()
+  .prop('office', S.ref('https://fastify/demo#/definitions/addressSchema')).required()
+
+const schema = { body: bodyJsonSchema }
+
+fastify.post('/the/url', { schema }, handler)
+```
+
+
+**`replace-way`**: refer to a shared schema to replace before the validation
+process.
+
+```js
+const sharedAddressSchema = {
+  $id: 'sharedAddress',
+  type: 'object',
+  required: ['line1', 'country', 'city', 'zipcode'],
+  properties: {
+    line1: { type: 'string' },
+    line2: { type: 'string' },
+    country: { type: 'string' },
+    city: { type: 'string' },
+    zipcode: { type: 'string' }
+  }
+}
+fastify.addSchema(sharedAddressSchema)
+
+const bodyJsonSchema = {
+  type: 'object',
+  properties: {
+    vacation: 'sharedAddress#'
+  }
+}
+
+const schema = { body: bodyJsonSchema }
+
+fastify.post('/the/url', { schema }, handler)
+```
+
+NB You can mix up the `$ref-way` and the `replace-way` when using
+`fastify.addSchema`.
