+
+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 = "0.2"
+```
+
+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)
+}
+```
+
+For more information about supported targets, entropy sources, `no_std` targets,
+crate features, WASM support and Custom RNGs see the
+[`getrandom` documentation](https://docs.rs/getrandom/latest) and
+[`getrandom::Error` documentation](https://docs.rs/getrandom/latest/getrandom/struct.Error.html).
+
+## Minimum Supported Rust Version
+
+This crate requires Rust 1.34.0 or later.
