+# TDLib C# example
+
+This is an example of building TDLib with `C++/CLI` support and an example of TDLib usage from C#.
+
+## Building TDLib
+
+* Download and install Microsoft Visual Studio 2015 or later.
+* 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 using `vcpkg`:
+```
+C:\src\vcpkg> .\vcpkg.exe install openssl:x64-windows openssl:x86-windows zlib:x64-windows zlib:x86-windows
+```
+* (Optional. For XML documentation generation.) Download [PHP](https://windows.php.net/download#php-7.2). Add the path to php.exe to the PATH environment variable.
+* 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.
+* Build `TDLib` with CMake enabling `.NET` support and specifying correct path to `vcpkg` toolchain file:
+```
+cd <path to TDLib sources>/example/csharp
+mkdir build
+cd build
+cmake -DTD_ENABLE_DOTNET=ON -DCMAKE_TOOLCHAIN_FILE=C:\src\vcpkg\scripts\buildsystems\vcpkg.cmake ../../..
+cmake --build . --config Release
+cmake --build . --config Debug
+```
+
+## Example of usage
+
+After `TDLib` is built you can open and run TdExample project.
+It contains a simple console C# application with implementation of authorization and message sending.
+Just open it with Visual Studio 2015 or 2017 and run.
+
+Also see TdExample.csproj for example of including TDLib in C# project with all native shared library dependencies.
