+*****
+Usage
+*****
+
+To use the fmt library, add :file:`format.h` and :file:`format.cc` from
+a `release archive <https://github.com/fmtlib/fmt/releases/latest>`_
+or the `Git repository <https://github.com/fmtlib/fmt>`_ to your project.
+Alternatively, you can :ref:`build the library with CMake <building>`.
+
+If you are using Visual C++ with precompiled headers, you might need to add
+the line ::
+
+   #include "stdafx.h"
+
+before other includes in :file:`format.cc`.
+
+.. _building:
+
+Building the library
+====================
+
+The included `CMake build script`__ can be used to build the fmt
+library on a wide range of platforms. CMake is freely available for
+download from http://www.cmake.org/download/.
+
+__ https://github.com/fmtlib/fmt/blob/master/CMakeLists.txt
+
+CMake works by generating native makefiles or project files that can
+be used in the compiler environment of your choice. The typical
+workflow starts with::
+
+  mkdir build          # Create a directory to hold the build output.
+  cd build
+  cmake <path/to/fmt>  # Generate native build scripts.
+
+where :file:`{<path/to/fmt>}` is a path to the ``fmt`` repository.
+
+If you are on a \*nix system, you should now see a Makefile in the
+current directory. Now you can build the library by running :command:`make`.
+
+Once the library has been built you can invoke :command:`make test` to run
+the tests.
+
+You can control generation of the make ``test`` target with the ``FMT_TEST``
+CMake option. This can be useful if you include fmt as a subdirectory in
+your project but don't want to add fmt's tests to your ``test`` target.
+
+If you use Windows and have Visual Studio installed, a :file:`FORMAT.sln`
+file and several :file:`.vcproj` files will be created. You can then build them
+using Visual Studio or msbuild.
+
+On Mac OS X with Xcode installed, an :file:`.xcodeproj` file will be generated.
+
+To build a `shared library`__ set the ``BUILD_SHARED_LIBS`` CMake variable to
+``TRUE``::
+
+  cmake -DBUILD_SHARED_LIBS=TRUE ...
+
+__ http://en.wikipedia.org/wiki/Library_%28computing%29#Shared_libraries
+
+Header-only usage with CMake
+============================
+
+You can add the ``fmt`` library directory into your project and include it in
+your ``CMakeLists.txt`` file::
+
+   add_subdirectory(fmt)
+
+or
+
+::
+
+   add_subdirectory(fmt EXCLUDE_FROM_ALL)
+
+to exclude it from ``make``, ``make all``, or ``cmake --build .``.
+
+You can detect and use an installed version of {fmt} as follows::
+
+   find_package(fmt)
+   target_link_libraries(<your-target> fmt::fmt)
+
+Setting up your target to use a header-only version of ``fmt`` is equaly easy::
+
+   target_link_libraries(<your-target> PRIVATE fmt-header-only)
+
+Building the documentation
+==========================
+
+To build the documentation you need the following software installed on your
+system:
+
+* `Python <https://www.python.org/>`_ with pip and virtualenv
+* `Doxygen <http://www.stack.nl/~dimitri/doxygen/>`_
+* `Less <http://lesscss.org/>`_ with ``less-plugin-clean-css``.
+  Ubuntu doesn't package the ``clean-css`` plugin so you should use ``npm``
+  instead of ``apt`` to install both ``less`` and the plugin::
+
+    sudo npm install -g less less-plugin-clean-css.
+
+First generate makefiles or project files using CMake as described in
+the previous section. Then compile the ``doc`` target/project, for example::
+
+  make doc
+
+This will generate the HTML documentation in ``doc/html``.
+  
+Android NDK
+===========
+
+fmt provides `Android.mk file`__ that can be used to build the library
+with `Android NDK <https://developer.android.com/tools/sdk/ndk/index.html>`_.
+For an example of using fmt with Android NDK, see the
+`android-ndk-example <https://github.com/fmtlib/android-ndk-example>`_
+repository.
+

+
+Homebrew
+========
+
+fmt can be installed on OS X using `Homebrew <http://brew.sh/>`_::
+
+  brew install fmt
