 You can run DDP on mnist example with 4 GPUs like this:
 
 ```bash
-python run.py trainer.gpus=4 +trainer.accelerator="ddp"
+python run.py trainer.gpus=4 +trainer.strategy=ddp
 ```
 
 ⚠️ When using DDP you have to be careful how you write your models - learn more [here](https://pytorch-lightning.readthedocs.io/en/latest/advanced/multi_gpu.html).
