+Intro
+=====
+
+The C++ version of libaddressinput library provides UI layout information and
+validation for address input forms.
+
+The library does not provide a UI. The user of the library must provide the user
+interface that uses libaddressinput. The user of the library must also provide a
+way to store data on disk and download data from the internet.
+
+The first client of the library is Chrome web browser. This motivates not
+providing UI or networking capabilities. Chrome will provide those.
+
+When including the library in your project, you can override the dependencies
+and include directories in libaddressinput.gypi to link with your own
+third-party libraries.
+
+Dependencies
+============
+
+The library depends on these tools and libraries:
+
+GYP: Generates the build files.
+Ninja: Executes the build files.
+GTest: Used for unit tests.
+Python: Used by GRIT, which generates localization files.
+
+Most of these packages are available on Debian-like distributions. You can
+install them with this command:
+
+$ sudo apt-get install gyp ninja-build libgtest-dev python
+
+Make sure that your version of GYP is at least 0.1~svn1395. Older versions of
+GYP do not generate the Ninja build files correctly. You can download a
+new-enough version from http://packages.ubuntu.com/saucy/gyp.
+
+If your distribution does not include the binary packages for the dependencies,
+you can download them from these locations:
+
+http://packages.ubuntu.com/saucy/gyp
+http://packages.ubuntu.com/saucy/ninja-build
+http://packages.ubuntu.com/saucy/libgtest-dev
+http://packages.ubuntu.com/saucy/python
+
+Alternatively, you can download, build, and install these tools and libraries
+from source code. Their home pages contain information on how to accomplish
+that.

+
+Build
+=====
+
+Building the library involves generating an out/Default/build.ninja file and
+running ninja:
+
+$ export GYP_GENERATORS='ninja'
+$ gyp --depth .
+$ ninja -C out/Default
+
+Overriding paths defined in the *.gyp files can be done by setting the
+GYP_DEFINES environment variable before running gyp:
+
+$ export GYP_DEFINES="gtest_dir='/xxx/include' gtest_src_dir='/xxx'"
+
+Test
+====
+
+This command will execute the unit tests for the library:
+
+$ out/Default/unit_tests
