+
+
+A Rust library for retrieving random data from (operating) system source. It is
+assumed that system always provides high-quality cryptographically secure random
+data, ideally backed by hardware entropy sources. This crate derives its name
+from Linux's `getrandom` function, but is cross platform, roughly supporting
+the same set of platforms as Rust's `std` lib.
+
+This is a low-level API. Most users should prefer using high-level random-number
+library like [`rand`].
+
+[`rand`]: https://crates.io/crates/rand
+
+## Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+getrandom = "0.1"
+```
+
+Then invoke the `getrandom` function:
+
+```rust
+fn get_random_buf() -> Result<[u8; 32], getrandom::Error> {
+    let mut buf = [0u8; 32];
+    getrandom::getrandom(&mut buf)?;
+    Ok(buf)
+}
+```
+
+## Features
+
+This library is `no_std` for every supported target. However, getting randomness
+usually requires calling some external system API. This means most platforms
+will require linking against system libraries (i.e. `libc` for Unix,
+`Advapi32.dll` for Windows, Security framework on iOS, etc...).
+
+The `log` library is supported as an optional dependency. If enabled, error
+reporting will be improved on some platforms.
+
+For the `wasm32-unknown-unknown` target, one of the following features should be
+enabled:
+
+-   [`wasm-bindgen`](https://crates.io/crates/wasm_bindgen)
+-   [`stdweb`](https://crates.io/crates/stdweb)
+
+By default, compiling `getrandom` for an unsupported target will result in
+a compilation error. If you want to build an application which uses `getrandom`
+for such target, you can either:
+- Use [`[replace]`][replace] or [`[patch]`][patch] section in your `Cargo.toml`
+to switch to a custom implementation with a support of your target.
+- Enable the `dummy` feature to have getrandom use an implementation that always
+fails at run-time on unsupported targets.
+
+[replace]: https://doc.rust-lang.org/cargo/reference/manifest.html#the-replace-section
+[patch]: https://doc.rust-lang.org/cargo/reference/manifest.html#the-patch-section
+
+## Minimum Supported Rust Version
+
+This crate requires Rust 1.32.0 or later.

+The `getrandom` library is distributed under either of
