 # TDLib Universal Windows Platform example
 
-Here are script for building TDLib SDK for universal windows platfrom and an example of its usage.
+This is an example of building TDLib SDK for Universal Windows Platform and an example of its usage from C#.
 
 ## Building SDK
 
-1. Install [vcpkg](https://github.com/Microsoft/vcpkg).
-
-2. With `vcpkg` install `zlib` and `openssl` for all UWP architectures.
+* Download and install Microsoft Visual Studio 2015+ with Windows 10 SDK. We recommend to use the latest available versions of Microsoft Visual Studio and Windows 10 SDK.
+* Download and install [CMake](https://cmake.org/download/).
+* Install [vcpkg](https://github.com/Microsoft/vcpkg#quick-start) or update it to the latest version using `vcpkg update` and following received instructions.
+* Install `zlib` and `openssl` for all UWP architectures using `vcpkg`:
 ```
-.\vcpkg.exe install openssl:arm-uwp openssl:arm64-uwp openssl:x64-uwp openssl:x86-uwp zlib:arm-uwp zlib:arm64-uwp zlib:x64-uwp zlib:x86-uwp
+C:\src\vcpkg> .\vcpkg.exe install openssl:arm-uwp openssl:x64-uwp openssl:x86-uwp zlib:arm-uwp zlib:x64-uwp zlib:x86-uwp
 ```
-3. Install 7z. You may also use zip or winrar.
-
-4. Run build.ps1 with `powershell`.
-Pass path to vcpkg as `-vcpkg-root` argument.
+* Download and install [gperf](https://sourceforge.net/projects/gnuwin32/files/gperf/3.0.1/). Add the path to gperf.exe to the PATH environment variable.
+* Download and install [7-Zip](http://www.7-zip.org/download.html) archiver, which is used by the `build.ps1` script to create a TDLib.UWP Visual Studio Extension. Add the path to 7z.exe to the PATH environment variable.
+  Alternatively `build.ps1` supports compressing using [WinRAR](https://en.wikipedia.org/wiki/WinRAR) with option `-compress winrar` and compressing using [zip](http://gnuwin32.sourceforge.net/packages/zip.htm) with `-compress zip`.
+* Build `TDLib` using provided `build.ps1` script (TDLib should be built 6 times for multiple platforms in Debug and Release configurations, so it make take few hours). Pass path to vcpkg.exe as `-vcpkg-root` argument:
 ```
-.\build.ps1 -vcpkg-root "~\vcpkg\"
+powershell -ExecutionPolicy ByPass .\build.ps1 -vcpkg_root C:\src\vcpkg
 ```
+If you need to restart the build from scratch, call `.\build.ps -mode clean` first.
+* Install Visual Studio Extension "TDLib for Universal Windows Platform" located at `build-uwp\vsix\tdlib.vsix`, which was created on the previous step by `build.ps1` script.
 
-If you wish to use `zip` or `WinRAR` instead of `7z` pass `-compress zip` or `-compress winrar`.
-
-The build process will take a lot of time, as TDLib will be built for multiple
-platforms in Debug and Release configurations. You may interrupt and resume the script at any moment.
-
-If you will need to restart the build from scratch, call `.\build.ps -mode "clean"` first.
-
-5. `tdlib.vsix` will be at `build-uwp\vsix\tdlib.vsix`. Open it and install the SDK.
+Now `TDLib` can be freely used from any UWP project, built in Visual Studio.
 
 ## Example of usage
-`app` directory contains a simple example of app for Universal Windows Plaform. Just open it with Visual Studio 2015 or 2017 and run.
+The `app/` directory contains a simple example of a C# application for Universal Windows Platform. Just open it with Visual Studio 2015 or 2017 and run.
