+
+This plugin add a handy parser for `multipart/form-data` by using `formidable` and provide a better integration between `multipart/form-data` and `fastify-swagger`
+
+## Install
+```
+npm install fastify-formidable --save
+
+yarn add fastify-formidable
+```
+
+## Usage
+
+```ts
+import FastifyFormidable from 'fastify-formidable'
+
+fastify.register(FastifyFormidable)
+
+fastify.post('/', async function(request, reply) {
+  // you need to call the parser if you do not pass any option through plugin registration
+  await request.parseMultipart()
+
+  // access files
+  request.files
+
+  // access body
+  // note that file fields will exist in body and it will becomes the file path saved on disk
+  request.body
+})
+
+// add content type parser which will automatic parse all `multipart/form-data` found
+fastify.register(FastifyFormidable, {
+  addContentTypeParser: true
+})
+
+// add `preValidation` hook which will automatic parse all `multipart/form-data` found
+fastify.register(FastifyFormidable, {
+  addHooks: true
+})
+```
+
+### Options
+
+#### options.formidable
+
+The options which will be directly passed to `formidable`.
+
+```ts
+import FastifyFormidable from 'fastify-formidable'
+
+fastify.register(FastifyFormidable, {
+  formidable: {
+    maxFileSize: 1000 
+  }
+})
+```
+
+See: [`formidable`](https://github.com/node-formidable/formidable#options)
+
+### Integration
+
+It is a known limitation for `fastify-multipart` integrate with `fastify-swagger` and this plugin provide a relatively simple solution for the integration.
+
+```ts
+import Fastify from 'fastify'
+import FastifyFormidable, { ajvBinaryFormat } from 'fastify-formidable'
+import FastifySwagger from 'fastify-swagger'
+
+const fastify = Fastify({
+  ajv: {
+    plugins: [ ajvBinaryFormat ]
+  }
+})
+
+fastify.register(FastifyFormidable, {
+  addContentTypeParser: true
+})
+
+fastify.register(FastifySwagger)
+```
