-Vorbis is a general purpose audio and music encoding format
-contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
-MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
-proprietary formats such as RealAudio G2 and Windows' flavor of the
-month), the Vorbis CODEC specification belongs to the public domain.
-All the technical details are published and documented, and any
-software entity may make full use of the format without license 
-fee, royalty or patent concerns.
-
-This package contains:
-
-* libvorbis, a BSD-style license software implementation of
-  the Vorbis specification by the Xiph.Org Foundation 
-  (http://www.xiph.org/) 
-
-* libvorbisfile, a BSD-style license convenience library
-  built on Vorbis designed to simplify common uses
-
-* libvorbisenc, a BSD-style license library that provides a simple,
-  programmatic encoding setup interface 
-
-* example code making use of libogg, libvorbis, libvorbisfile and
-  libvorbisenc
-
-WHAT'S HERE:
-
-This source distribution includes libvorbis and an example
-encoder/player to demonstrate use of libvorbis as well as
-documentation on the Ogg Vorbis audio coding format.
-
-You'll need libogg (distributed separately) to compile this library.
-A more comprehensive set of utilities is available in the vorbis-tools
-package.

-
-BUILDING FROM TRUNK:
-
-Development source is under subversion revision control at 
-https://svn.xiph.org/trunk/vorbis/. You will also need the 
-newest versions of autoconf, automake, libtool and pkg-config in
-order to compile Vorbis from development source. A configure script
-is provided for you in the source tarball distributions.
-
-  [update or checkout latest source]
-  ./autogen.sh
-  make
-
-and as root if desired:
-
-  make install
-
-This will install the Vorbis libraries (static and shared) into
-/usr/local/lib, includes into /usr/local/include and API manpages
-(once we write some) into /usr/local/man.
-
-Documentation building requires xsltproc and pdfxmltex.
-
-BUILDING FROM TARBALL DISTRIBUTIONS:
-
-  ./configure
-  make
-
-and optionally (as root):
-  make install
-
-BUILDING RPMS:
-
-after normal configuring:
-
-  make dist
-  rpm -ta libvorbis-<version>.tar.gz
-
-BUILDING ON MACOS 9:
-
-Vorbis on MacOS 9 is built using Metroworks CodeWarrior.  To build it, 
-first verify that the Ogg libraries are already built following the
-instructions in the Ogg module README.  Open vorbis/mac/libvorbis.mcp,
-switch to the "Targets" pane, select everything, and make the project.
-Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in
-that order).  In vorbis/mac/Output you will now have both debug and final
-versions of Vorbis shared libraries to link your projects against.
-
-To build a project using Ogg Vorbis, add access paths to your
-CodeWarrior project for the ogg/include, ogg/mac/Output,
-vorbis/include, and vorbis/mac/Output folders.  Be sure that
-"interpret DOS and Unix paths" is turned on in your project; it can
-be found in the "access paths" pane in your project settings.  Now
-simply add the shared libraries you need to your project (OggLib and
-VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h"
-wherever you need to access Ogg and Vorbis functionality.

+## Building ##
+
+#### Building from master ####
+
+Development source is under git revision control at
+https://gitlab.xiph.org/xiph/vorbis.git. You will also need the
+newest versions of autoconf, automake, libtool and pkg-config in
+order to compile Vorbis from development source. A configure script
+is provided for you in the source tarball distributions.

+
+This will install the Vorbis libraries (static and shared) into
+/usr/local/lib, includes into /usr/local/include and API manpages
+(once we write some) into /usr/local/man.
+
+Documentation building requires xsltproc and pdfxmltex.
+
+#### Building from tarball distributions ####
+
+    ./configure
+    make
+
+and optionally (as root):
+
+    make install
+
+#### Building RPM packages ####
+
+after normal configuring:
+
+    make dist
+    rpm -ta libvorbis-<version>.tar.gz
+
+## Building with CMake ##
+
+Ogg supports building using [CMake](https://cmake.org/). CMake is a meta build system that generates native projects for each platform.
+To generate projects just run cmake replacing `YOUR-PROJECT-GENERATOR` with a proper generator from a list [here](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html):
+
+    cmake -G YOUR-PROJECT-GENERATOR .
+
+Note that by default cmake generates projects that will build static libraries.
+To generate projects that will build dynamic library use `BUILD_SHARED_LIBS` option like this:
+
+    cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 .
+
+After projects are generated use them as usual
+
+#### Building on Windows ####
+
+Use proper generator for your Visual Studio version like:
+
+    cmake -G "Visual Studio 12 2013" .
+
+#### Building on Mac OS X ####
+
+Use Xcode generator. To build framework run:
+
+    cmake -G Xcode -DBUILD_FRAMEWORK=1 .
+
+#### Building on Linux ####
+
+Use Makefile generator which is default one.
+
+    cmake .
+    make
