    This method can be used to run multiple clients at once and can be found directly in the ``pyrogram`` package.

    If you want to run a single client, you can use Client's bound method :meth:`~pyrogram.Client.run`.

    Parameters:
        clients (List of :obj:`~pyrogram.Client`):
            A list of client objects to run.

        sequential (``bool``, *optional*):
            Pass True to run clients sequentially.
            Defaults to False (run clients concurrently)

    Example:
        .. code-block:: python

            import asyncio
            from pyrogram import Client, compose


            async def main():
                apps = [
                    Client("account1"),
                    Client("account2"),
                    Client("account3")
                ]

                ...

                await compose(apps)


            asyncio.run(main())
