## Prepare folder
The build is done in **Visual Studio 2022** with **10.0.22000.0** SDK version.
Choose an empty folder for the future build, for example **D:\\TBuild**. It will be named ***BuildPath*** in the rest of this document. Create two folders there, ***BuildPath*\\ThirdParty** and ***BuildPath*\\Libraries**.
All commands (if not stated otherwise) will be launched from **x64 Native Tools Command Prompt for VS 2022.bat** (should be in **Start Menu > Visual Studio 2022** menu folder). Pay attention not to use any other Command Prompt.
### Obtain your API credentials
You will require **api_id** and **api_hash** to access the Telegram API servers. To learn how to obtain them [click here][api_credentials].
## Install third party software
* Download **Python 3.9** installer from [https://www.python.org/downloads/](https://www.python.org/downloads/) and install to ***BuildPath*\\ThirdParty\\Python39** with adding to PATH
* Download **CMake 3.21 or later** installer from [https://cmake.org/download/](https://cmake.org/download/) and install to ***BuildPath*\\ThirdParty\\cmake**
* Download **Git** installer from [https://git-scm.com/download/win](https://git-scm.com/download/win) and install it.
Open **x64 Native Tools Command Prompt for VS 2022.bat**, go to ***BuildPath*** and run
python -m pip install pywin32
## Clone source code and prepare libraries
Open **x64 Native Tools Command Prompt for VS 2022.bat**, go to ***BuildPath*** and run
git clone --recursive https://github.com/telegramdesktop/tdesktop.git
tdesktop\Telegram\build\prepare\win.bat
## Build the project
Go to ***BuildPath*\\tdesktop\\Telegram** and run (using [your **api_id** and **api_hash**](#obtain-your-api-credentials))
configure.bat x64 -D TDESKTOP_API_ID=YOUR_API_ID -D TDESKTOP_API_HASH=YOUR_API_HASH
* Open ***BuildPath*\\tdesktop\\out\\Telegram.sln** in Visual Studio 2022
* Select Telegram project and press Build > Build Telegram (Debug and Release configurations)
* The result Telegram.exe will be located in **D:\TBuild\tdesktop\out\Debug** (and **Release**)
### Qt Visual Studio Tools
