    Here is a brief explanation of the service configuration:
 
    - `After=network.target` --- indicates that the application should be launched after the Internet module is loaded.
-   - `Environment=BOT_TOKEN=<token>` --- sets the environment variable `BOT_TOKEN`.
-     Add other `Environment` entries if you need multiple environment variables.
+   - `WorkingDirectory=<bot-directory-path>` --- sets the current working directory of the process.
+     This allows you to use relative assets, such as the `.env` file, which contains all the necessary environment variables.
    - `ExecStart=<start-command>` --- sets the startup command.
    - `Restart=on-failure` --- indicates that the application should restart after a crash.
    - `WantedBy=multi-user.target` --- defines the system state in which the service should be launched.
