+# RUIN - Rust Native Application Framework
+
+A layered architecture for fast, native, cross-platform applications.
+
+RUIN is a modern asynchronous runtime for interactive Rust applications on personal computers. It has a simple
+threading and scheduling model, fast asynchronous I/O (io_uring on Linux, kqueue on macOS, and IOCP on windows),
+and several libraries to enable building modern, reactive applications.
+
+## Runtime
+
+RUIN's core runtime is provided in [`ruin-runtime`](./lib/runtime/).
+
+The runtime is non-workstealing with no threadpool. When a RUIN application starts, it runs a simple event loop on the
+main thread.
