+
+`futures-rs` is a library providing the foundations for asynchronous programming in Rust.
+It includes key trait definitions like `Stream`, as well as utilities like `join!`,
+`select!`, and various futures combinator methods which enable expressive asynchronous
+control flow.
+
+## Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+futures = "0.3"
+```
+
+The current `futures` requires Rust 1.45 or later.
+
+### Feature `std`
+
+Futures-rs works without the standard library, such as in bare metal environments.
+However, it has a significantly reduced API surface. To use futures-rs in
+a `#[no_std]` environment, use:
+
+```toml
+[dependencies]
+futures = { version = "0.3", default-features = false }
+```
