+//! # nginx-sys
+//!
+//! The `nginx-sys` crate provides low-level bindings for the nginx C API, allowing Rust applications to interact with nginx servers and modules.
+//!
+//! ## Usage
+//!
+//! Add `nginx-sys` as a dependency in your `Cargo.toml`:
+//!
+//! ```toml
+//! [dependencies]
+//! nginx-sys = "0.1.0"
+//! ```
+//!
+//! ## Features
+//!
+//! - `build`: Enables the build scripts to compile and link against the nginx C library. This feature is enabled by default.
+//!
+//! ## Examples
+//!
+//! ### Get Nginx Version
+//!
+//! This example demonstrates how to retrieve the version of the nginx server.
+//!
+//! ```rust,no_run
+//! use nginx_sys::nginx_version;
+//!
+//! fn main() {
+//!     let version = unsafe { nginx_version() };
+//!     println!("Nginx version: {}", version);
+//! }
+//! ```
