 - In Visual Studio, Clone the Heroku git repository and add some standard .gitignore .gitattributes files
 - In this repository folder, create a new .NET Console project with this Program.cs file
 - Add these Nuget packages: WTelegramClient and Npgsql
-- In Project properties > Debug > Environment variables, configure the same values for DATABASE_URL, api_hash, phone_number
+- In Project properties > Debug > Launch Profiles > Environment variables, configure the same values for DATABASE_URL, api_hash, phone_number
 - Run the project in Visual Studio. The first time, it should ask you interactively for elements to complete the connection
 - On the following runs, the PostgreSQL database contains the session data and it should connect automatically
 - You can test the userbot by sending him "Ping" in private message (or saved messages). It should respond with "Pong"
