+The LLDB Debugger
+=================
+
+Welcome to the LLDB version |release| documentation!
+
+LLDB is a next generation, high-performance debugger. It is built as a set of
+reusable components which highly leverage existing libraries in the larger LLVM
+Project, such as the Clang expression parser and LLVM disassembler.
+
+LLDB is the default debugger in Xcode on macOS and supports debugging C,
+Objective-C and C++ on the desktop and iOS devices and simulator.
+
+All of the code in the LLDB project is available under the
+`"Apache 2.0 License with LLVM exceptions"`_.
+
+.. _"Apache 2.0 License with LLVM exceptions": https://llvm.org/docs/DeveloperPolicy.html#new-llvm-project-license-framework
+
+Using LLDB
+----------
+
+For an introduction into the LLDB command language, head over to the `LLDB
+Tutorial <https://lldb.llvm.org/use/tutorial.html>`_. For users already familiar
+with GDB there is a cheat sheet listing common tasks and their LLDB equivalent
+in the `GDB to LLDB command map <https://lldb.llvm.org/use/map.html>`_.
+
+There are also multiple resources on how to script LLDB using Python `Python
+Reference <https://lldb.llvm.org/use/python-reference.html>`_ is a great
+starting point for that.
+
+Compiler Integration Benefits
+-----------------------------
+
+LLDB converts debug information into Clang types so that it can
+leverage the Clang compiler infrastructure. This allows LLDB to support the
+latest C, C++, Objective-C and Objective-C++ language features and runtimes in
+expressions without having to reimplement any of this functionality. It also
+leverages the compiler to take care of all ABI details when making functions
+calls for expressions, when disassembling instructions and extracting
+instruction details, and much more.
+
+The major benefits include:
+
+- Up to date language support for C, C++, Objective-C
+- Multi-line expressions that can declare local variables and types
+- Utilize the JIT for expressions when supported
+- Evaluate expression Intermediate Representation (IR) when JIT can't be used
+
+Reusability
+-----------
+
+The LLDB debugger APIs are exposed as a C++ object oriented interface in a
+shared library. The lldb command line tool links to, and uses this public API.
+On macOS the shared library is exposed as a framework named LLDB.framework,
+and Unix systems expose it as lldb.so. The entire API is also then exposed
+through Python script bindings which allow the API to be used within the LLDB
+embedded script interpreter, and also in any python script that loads the
+lldb.py module in standard python script files. See the Python Reference page
+for more details on how and where Python can be used with the LLDB API.
+
+Sharing the LLDB API allows LLDB to not only be used for debugging, but also
+for symbolication, disassembly, object and symbol file introspection, and much
+more.
+
+Platform Support
+----------------
+
+LLDB is known to work on the following platforms, but ports to new platforms
+are welcome:
+
+* macOS desktop user space debugging for i386 and x86_64
+* iOS, tvOS, and watchOS simulator debugging on i386 and x86_64
+* iOS, tvOS, and watchOS device debugging on ARM and AArch64
+* Linux local user-space debugging for i386, x86_64 and PPC64le
+* FreeBSD local user-space debugging for i386 and x86_64
+* Windows local user-space debugging for i386 (*)
+
+(*) Support for Windows is under active development. Basic functionality is
+expected to work, with functionality improving rapidly.
+
+Get Involved
+------------
+
+Check out the LLVM source-tree with git and find the sources in the `lldb`
+subdirectory:
+
+::
+
+  > git clone https://github.com/llvm/llvm-project.git
+
+Note that LLDB generally builds from top-of-trunk using CMake and Ninja.
+Additionally it builds:
+
+* on macOS with a :ref:`generated Xcode project <CMakeGeneratedXcodeProject>`
+* on Linux and FreeBSD with Clang and libstdc++/libc++
+* on NetBSD with GCC/Clang and libstdc++/libc++
+* on Windows with a generated project for VS 2017 or higher
+
+See the :doc:`LLDB Build Page <resources/build>` for build instructions.
+
+Discussions about LLDB should go to the `lldb-dev
+<http://lists.llvm.org/mailman/listinfo/lldb-dev>`__ mailing list. Commit
+messages are automatically sent to the `lldb-commits
+<http://lists.llvm.org/mailman/listinfo/lldb-commits>`__ mailing list , and
+this is also the preferred mailing list for patch submissions.
+
+See the :doc:`Projects page <status/projects>` if you are looking for some
+interesting areas to contribute to lldb.
