+# Changelog
+
+## Version 1.1
+
+*TBD*
+
+[View Issues][v1.1-issues]
+
+**Features:**
+
+- Added `BUILD_TESTS` CMake configuration variable
+
+## Version 1.0
+
+*March 27, 2017*
+
+[View Issues][v1.0-issues]
+
+**Features:**
+
+- Using CMake version 3.3
+- Installs LibWebRTC as a CMake package
+- Support for `gn`-based releases
+- Synchronize depot_tools with WebRTC's commit date
+- `TARGET_OS` and `TARGET_CPU` CMake config variables
+- `WEBRTC_REVISION` and `WEBRTC_BRANCH_HEAD` CMake config variables
+- x86 support under Windows
+- Better host OS and CPU architecture detection
+- pkg-config file generation
+- Deprecated shared library support
+- Debug mode support
+- .zip package for Windows, .tar.gz for Unix
+- Basic .deb and .rpm package generation
+
+**Fixes:**
+
+- Removed package.json and Jake support, focusing on CMake only
+- Refactored source code, removed Targets folder
+- Run commands with `cmake -E env`, no more Prefix File Trick
+- No more `merge_libs.py` call, use CMake to create the library
+- Removed the peer connection sample, wrote a little executable for tests
+- Removed FindLibWebRTC.cmake, defined CMake package files
+- Removed depot_tools git submodule
+- Retrieve the Linux sysroot before calling the generator
+- Removed support for releases older than January 1st, 2017 for now
+- Removed libwebrtc-chromium-deps repository
+- Wrote libwebrtc_execute macro
+- Created uninstall target
+- Removed BUILD_TESTS flag for now
+- Fixed static linking

-It also produces a `pkg-config` file if you prefer the classic way:
+## Prerequisites
+
+- CMake 3.9 or later
+- Python 2.7 (optional for Windows since it will use the interpreter located
+  inside the `depot_tools` installation)
+
+### Debian & Ubuntu
+
+- Required development packages:
 
 ```
-$ g++ `pkg-config --cflags LibWebRTC` main.cpp -o main `pkg-config --libs LibWebRTC`
+# apt-get install build-essential libglib2.0-dev libgtk2.0-dev libxtst-dev \
+                  libxss-dev libpci-dev libdbus-1-dev libgconf2-dev \

+- GCC & G++ 4.8 or later, for C++11 support
+
+### macOS
+
+- OS X 10.11 or later
+- Xcode 7.3.1 or later
+
+### Windows
+
+- Windows 7 x64 or later
+- Visual Studio 2015/2017
+
+  Make sure that you install the following components:
+  
+  - Visual C++, which will select three sub-categories including MFC
+  - Universal Windows Apps Development Tools
+    - Tools (1.4.1) and Windows 10 SDK (**10.0.14393**)
+
+- [Windows 10 SDK][w10sdk] with **Debugging Tools for Windows** or
+  [Windows Driver Kit 10][wdk10] installed in the same Windows 10 SDK
+  installation directory.
+
+## Getting sources
+Clone the repository and run script to fetch WebRTC sources.
+You can pass WebRTC version (branch) to script to fetch specific version.
+
+```
+git clone https://github.com/UltraCoderRU/libwebrtc.git
+cd libwebrtc
+python3 sync.py [WEBRTC_VERSION]
+```
+
+## Compiling
+
+Create an output directory, browse inside it, then run CMake to configure project.
+
+```
+mkdir build
+cd build
+cmake -G Ninja -DCMAKE_BUILD_TYPE=<Debug/Release> -DCMAKE_INSTALL_PREFIX=<install_path> ..
+```
+
+After configuration build library using standard CMake commands.
+
+```
+cmake --build .
+cmake --install .
+```
+
+The library will be located inside the `lib` subdirectory of the `<install_path>`.
+The `include` subdirectory will contain the header files.
+CMake scripts will be placed inside the `lib/cmake/LibWebRTC` subdirectory.
+
+## Using WebRTC in your project
+
+To import LibWebRTC into your CMake project use `find_package`:
+```cmake
+find_package(LibWebRTC REQUIRED)
+include(${LIBWEBRTC_USE_FILE})
+
+target_link_libraries(my-app ${LIBWEBRTC_LIBRARIES})
+```
+
+You should add library installation path to `CMAKE_INSTALL_PREFIX` variable
+while configuring your project:
+```
+cmake -DCMAKE_PREFIX_PATH=<install_path> ...
+```
+
+## Configuration
+
+The library will be compiled and usable on the same host's platform and
+architecture. Here are some CMake flags which could be useful if you need to
+perform cross-compiling.
+
+- **GN_EXTRA_ARGS**
+
+    Add extra arguments to the `gn gen --args` parameter.
+
+- **NINJA_ARGS**
+
+    Arguments to pass while executing the `ninja` command.

+## Acknowledgements
 
-### Debian & Ubuntu
+Many thanks to Dr. Alex Gouaillard for being an excellent mentor for this
+project.

-
-### macOS
-
-- OS X 10.11 or later,
-- Xcode 7.3.1 or later
-
-### Windows
-
-* Windows 7 x64 or later,
-* Visual Studio 2015 **with updates** - Download the [Installer][vs2015-installer]
-
-  Make sure that you install the following components:
-  
-  * Visual C++, which will select three sub-categories including MFC
-  * Universal Windows Apps Development Tools > Tools
-  * Universal Windows Apps Development Tools > Windows 10 SDK (**10.0.10586**)
-
-## Compiling
-
-Clone the repository, initialize the submodules if `depot_tools` is not
-installed on your system or not defined inside your `PATH` environment variable.
-Create an output directory, browse inside it, then run CMake.
-
-```
-$ git clone https://github.com/aisouard/libwebrtc.git
-$ cd libwebrtc
-$ git submodule init
-$ git submodule update
-$ mkdir out
-$ cd out
-$ cmake ..
-```
-
-Windows users will have to open the `libwebrtc.sln` located inside the current
-directory output directory and build the `ALL_BUILD` project.
-
-Unix users will just have to run the following `make` commands.
-
-```
-$ make
-# make install
-```
-
-The library will be located inside the `lib` folder of the current output
-directory. The `include` folder will contain the header files. CMake scripts
-will be placed inside the `lib/cmake/LibWebRTC` directory.
-
-## Using WebRTC in your project
-
-At the time of writing this README file, there's no proper way to detect any
-installation of the WebRTC library and header files. In the meantime, this CMake
-script generates and declares a `LibWebRTC` package that will be very easy to
-use for your projects.
-
-All you have to do is include the package, then embed the "use file" that will
-automatically find the required libraries, define the proper compiling flags and
-include directories.
-
-```
-find_package(LibWebRTC REQUIRED)
-include(${LIBWEBRTC_USE_FILE})
-
-target_link_libraries(my-app ${LIBWEBRTC_LIBRARIES})
-```
-
-A pkg-config file is also provided, you can obtain the required compiler and
-linker flags by specifying `LibWebRTC` as the package name.
-
-```
-$ pkg-config --cflags --libs LibWebRTC
-```
-
-## Configuration
-
-The library will be compiled and usable on the same host's platform and
-architecture. Here are some CMake flags which could be useful if you need to
-perform cross-compiling.
-
-- **BUILD_DEB_PACKAGE**
-
-    Generate Debian package, defaults to OFF, available under Linux only.
-
-- **BUILD_RPM_PACKAGE**
-
-    Generate Red Hat package, defaults to OFF, available under Linux only.
-
-- **BUILD_TESTS**
-
-    Build WebRTC tests. (not supported yet)
-
-- **BUILD_SHARED_LIB**
-
-    Defaults to OFF, will define the `component_build` gn argument to `true` if
-    enabled. This option will build a shared library instead of a static one.
-
-- **NINJA_ARGS**
-
-    Arguments to pass while executing the `ninja` command. For instance, you can
-    define the number of cores you would like to use, in order to speed-up the
-    build process:
-    
-    `cmake -DNINJA_ARGS="-j 4" ..`
-
-- **TARGET_OS**
-
-    Target operating system, the value will be used inside the `--target_os`
-    argument of the `gn gen` command. The value **must** be one of the following:
-    
-    - `android`
-    - `chromeos`
-    - `ios`
-    - `linux`
-    - `mac`
-    - `nacl`
-    - `win`
-
-- **TARGET_CPU**
-
-    Target architecture, the value will be used inside the `--target_cpu`
-    argument of the `gn gen` command. The value **must** be one of the following:
-    
-    - `x86`
-    - `x64`
-    - `arm`
-    - `arm64`
-    - `mipsel`
-
-## Contributing
-
-Feel free to open an issue if you wish a bug to be fixed, to discuss a new
-feature or to ask a question. I'm open to pull requests, as long as your
-modifications are working on the three major OS (Windows, macOS and Linux).
-
-Don't forget to put your name and e-mail address inside the `AUTHORS` file!
-You can also reach me on [Twitter][twitter] for further discussion.
