+# Rusty HTTP Server
+
+Simple and scalable HTTP server implemented purely in Rust.
+
+Heavily based on: [**mtcp-rs**](https://crates.io/crates/mtcp-rs)
+
+## Environment Variables
+
+The following environment variables can be used to configure the server:
+
+- **`HTTP_PUBLIC_PATH`:** The path to serve files from (default: `<exe_path>/public`)
+- **`HTTP_BIND_ADDRESS`:** The local IP address where to listen for incoming connections (default: `0.0.0.0`)
+- **`HTTP_PORT_NUMBER`:** The port number to listen for incoming connections (default: `8080`)
+- **`HTTP_THREADS`:** The number of worker threads (default: detect automatically, one thread per CPU core)
+- **`RUST_LOG`:** Controls the log level (see [`env_logger`](https://docs.rs/env_logger/latest/env_logger/) for details!)
+
+## Supported Platforms
+
+The following platforms are officially supported:
+
+- Microsoft Windows
+- Linux
+- FreeBSD
+
+These platforms should work too, but are *not* tested extensively:
+
+- OpenBSD
+- NetBSD
+- DragonFly BSD
+- macOS
+
