-# The LLVM Compiler Infrastructure
-
-Welcome to the LLVM project!
-
-This repository contains the source code for LLVM, a toolkit for the
-construction of highly optimized compilers, optimizers, and run-time
-environments.
-
-The LLVM project has multiple components. The core of the project is
-itself called "LLVM". This contains all of the tools, libraries, and header
-files needed to process intermediate representations and convert them into
-object files. Tools include an assembler, disassembler, bitcode analyzer, and
-bitcode optimizer.
-
-C-like languages use the [Clang](http://clang.llvm.org/) frontend. This
-component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode
--- and from there into object files, using LLVM.
-
-Other components include:
-the [libc++ C++ standard library](https://libcxx.llvm.org),
-the [LLD linker](https://lld.llvm.org), and more.
