+Getting Started: Building and Running lld
+=========================================
+
+This page gives you the shortest path to checking out and building lld. If you
+run into problems, please file bugs in the `LLVM Bugzilla`__
+
+__ http://llvm.org/bugs/
+
+Building lld
+------------
+
+On Unix-like Systems
+~~~~~~~~~~~~~~~~~~~~
+
+1. Get the required tools.
+
+  * `CMake 2.8`_\+.
+  * make (or any build system CMake supports).
+  * `Clang 3.1`_\+ or GCC 4.7+ (C++11 support is required).
+
+    * If using Clang, you will also need `libc++`_.
+  * `Python 2.4`_\+ (not 3.x) for running tests.
+
+.. _CMake 2.8: http://www.cmake.org/cmake/resources/software.html
+.. _Clang 3.1: http://clang.llvm.org/
+.. _libc++: http://libcxx.llvm.org/
+.. _Python 2.4: http://python.org/download/
+
+2. Check out LLVM::
+
+     $ cd path/to/llvm-project
+     $ svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
+
+3. Check out lld::
+
+     $ cd llvm/tools
+     $ svn co http://llvm.org/svn/llvm-project/lld/trunk lld
+
+  * lld can also be checked out to ``path/to/llvm-project`` and built as an external
+    project.
+
+4. Build LLVM and lld::
+
+     $ cd path/to/llvm-build/llvm (out of source build required)
+     $ cmake -G "Unix Makefiles" path/to/llvm-project/llvm
+     $ make
+
+  * If you want to build with clang and it is not the default compiler or
+    it is installed in an alternate location, you'll need to tell the cmake tool
+    the location of the C and C++ compiler via CMAKE_C_COMPILER and
+    CMAKE_CXX_COMPILER. For example::
+
+        $ cmake -DCMAKE_CXX_COMPILER=/path/to/clang++ -DCMAKE_C_COMPILER=/path/to/clang ...
+
+5. Test::
+
+     $ make check-lld
+
+Using Visual Studio
+~~~~~~~~~~~~~~~~~~~
+
+#. Get the required tools.
+
+  * `CMake 2.8`_\+.
+  * `Visual Studio 12 (2013) or later`_ (required for C++11 support)
+  * `Python 2.4`_\+ (not 3.x) for running tests.
+
+.. _CMake 2.8: http://www.cmake.org/cmake/resources/software.html
+.. _Visual Studio 12 (2013) or later: http://www.microsoft.com/visualstudio/11/en-us
+.. _Python 2.4: http://python.org/download/
+
+#. Check out LLVM::
+
+     $ cd path/to/llvm-project
+     $ svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
+
+#. Check out lld::
+
+     $ cd llvm/tools
+     $ svn co http://llvm.org/svn/llvm-project/lld/trunk lld
+
+  * lld can also be checked out to ``path/to/llvm-project`` and built as an external
+    project.
+
+#. Generate Visual Studio project files::
+
+     $ cd path/to/llvm-build/llvm (out of source build required)
+     $ cmake -G "Visual Studio 11" path/to/llvm-project/llvm
+
+#. Build
+
+  * Open LLVM.sln in Visual Studio.
+  * Build the ``ALL_BUILD`` target.
+
+#. Test
+
+  * Build the ``lld-test`` target.
