+### fast-json-stringify Standalone
+
+`fast-json-stringify@v4.1.0` introduces the [standalone feature](https://github.com/fastify/fast-json-stringify#standalone) that let you to pre-compile your schemas and use them in your application for a faster startup.
+
+To use this feature, you must be aware of the following:
+
+1. You must generate and save the application's compiled schemas.
+2. Read the compiled schemas from the file and provide them back to your Fastify application.
+
+
+#### Generate and save the compiled schemas
+
+Fastify helps you to generate the serialization schemas functions and it is your choice to save them where you want.
+To accomplish this, you must use a new compiler: `@fastify/fast-json-stringify-compiler/standalone`.
+
+You must provide 2 parameters to this compiler:
+
+- `readMode: false`: a boolean to indicate that you want generate the schemas functions string.
+- `storeFunction`" a sync function that must store the source code of the schemas functions. You may provide an async function too, but you must manage errors.
+
+When `readMode: false`, **the compiler is meant to be used in development ONLY**.
+
+
+```js
+const { StandaloneSerializer } = require('@fastify/fast-json-stringify-compiler')
+
+const factory = StandaloneSerializer({
+  readMode: false,
+  storeFunction (routeOpts, schemaSerializationCode) {
+    // routeOpts is like: { schema, method, url, httpStatus }
+    // schemaSerializationCode is a string source code that is the compiled schema function
+    const fileName = generateFileName(routeOpts)
+    fs.writeFileSync(path.join(__dirname, fileName), schemaSerializationCode)
+  }
+})
+
+const app = fastify({
+  jsonShorthand: false,
+  schemaController: {
+    compilersFactory: {
+      buildSerializer: factory
+    }
+  }
+})
+
+// ... add all your routes with schemas ...
+
+app.ready().then(() => {
+  // at this stage all your schemas are compiled and stored in the file system
+  // now it is important to turn off the readMode
+})
+```
+
+#### Read the compiled schemas functions
+
+At this stage, you should have a file for every route's schema.
+To use them, you must use the `@fastify/fast-json-stringify-compiler/standalone` with the parameters:
+
+- `readMode: true`: a boolean to indicate that you want read and use the schemas functions string.
+- `restoreFunction`" a sync function that must return a function to serialize the route's payload.
+
+Important keep away before you continue reading the documentation:
+
+- when you use the `readMode: true`, the application schemas are not compiled (they are ignored). So, if you change your schemas, you must recompile them!
+- as you can see, you must relate the route's schema to the file name using the `routeOpts` object. You may use the `routeOpts.schema.$id` field to do so, it is up to you to define a unique schema identifier.
+
+```js
+const { StandaloneSerializer } = require('@fastify/fast-json-stringify-compiler')
+
+const factory = StandaloneSerializer({
+  readMode: true,
+  restoreFunction (routeOpts) {
+    // routeOpts is like: { schema, method, url, httpStatus }
+    const fileName = generateFileName(routeOpts)
+    return require(path.join(__dirname, fileName))
+  }
+})
+
+const app = fastify({
+  jsonShorthand: false,
+  schemaController: {
+    compilersFactory: {
+      buildSerializer: factory
+    }
+  }
+})
+
+// ... add all your routes with schemas as before...
+
+app.listen({ port: 3000 })
+```
+
 ### How it works
 
 This module provide a factory function to produce [Serializer Compilers](https://www.fastify.io/docs/latest/Reference/Server/#serializercompiler) functions.
