+# Unicorn
+
+Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework
+based on [QEMU](http://qemu.org).
+
+Unicorn offers some unparalleled features:
+
+- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, PowerPC, RISCV, SPARC, S390X, TriCore and X86 (16, 32, 64-bit)
+- Clean/simple/lightweight/intuitive architecture-neutral API
+- Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal, Haskell, Pharo, and Lua.
+- Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
+- High performance via Just-In-Time compilation
+- Support for fine-grained instrumentation at various levels
+- Thread-safety by design
+- Distributed under free software license GPLv2

-Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework
-based on [QEMU](http://qemu.org).
-
-Unicorn offers some unparalleled features:
-
-- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, PowerPC, RISCV, SPARC, S390X, TriCore and X86 (16, 32, 64-bit)
-- Clean/simple/lightweight/intuitive architecture-neutral API
-- Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal, Haskell, Pharo, and Lua.
-- Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
-- High performance via Just-In-Time compilation
-- Support for fine-grained instrumentation at various levels
-- Thread-safety by design
-- Distributed under free software license GPLv2
