-- [API Documentation](https://docs.rs/actix-multipart)
-- Minimum Supported Rust Version (MSRV): 1.68
+Multipart request & form support for Actix Web.
+
+The [`Multipart`] extractor aims to support all kinds of `multipart/*` requests, including `multipart/form-data`, `multipart/related` and `multipart/mixed`. This is a lower-level extractor which supports reading [multipart fields](Field), in the order they are sent by the client.
+
+Due to additional requirements for `multipart/form-data` requests, the higher level [`MultipartForm`] extractor and derive macro only supports this media type.
+
+## Examples
+
+```rust
+use actix_web::{post, App, HttpServer, Responder};
+
+use actix_multipart::form::{json::Json as MpJson, tempfile::TempFile, MultipartForm};
+use serde::Deserialize;
+
+#[derive(Debug, Deserialize)]
+struct Metadata {
+    name: String,
+}
+
+#[derive(Debug, MultipartForm)]
+struct UploadForm {
+    #[multipart(limit = "100MB")]
+    file: TempFile,
+    json: MpJson<Metadata>,
+}
+
+#[post("/videos")]
+pub async fn post_video(MultipartForm(form): MultipartForm<UploadForm>) -> impl Responder {
+    format!(
+        "Uploaded file {}, with size: {}",
+        form.json.name, form.file.size
+    )
+}
+
+#[actix_web::main]
+async fn main() -> std::io::Result<()> {
+    HttpServer::new(move || App::new().service(post_video))
+        .bind(("127.0.0.1", 8080))?
+        .run()
+        .await
+}
+```
+
+cURL request:
+
+```sh
+curl -v --request POST \
+  --url http://localhost:8080/videos \
+  -F 'json={"name": "Cargo.lock"};type=application/json' \
+  -F file=@./Cargo.lock

+
+Integration testing tools for Actix Web applications.
+
+The main integration testing tool is [`TestServer`]. It spawns a real HTTP server on an unused port and provides methods that use a real HTTP client. Therefore, it is much closer to real-world cases than using `init_service`, which skips HTTP encoding and decoding.
+
+## Examples
+
+```rust
+use actix_web::{get, web, test, App, HttpResponse, Error, Responder};
+
+#[get("/")]
+async fn my_handler() -> Result<impl Responder, Error> {
+    Ok(HttpResponse::Ok())
+}
+
+#[actix_rt::test]
+async fn test_example() {
+    let srv = actix_test::start(||
+        App::new().service(my_handler)
+    );
+
+    let req = srv.get("/");
+    let res = req.send().await.unwrap();
+
+    assert!(res.status().is_success());
+}
+```
