###### New project Quick Start    
To start a new project define these two files.   

1. [Define a LightningModule](/LightningModule/RequiredTrainerInterface/#template-model-definition)  
2. Pick a trainer      
    - [Basic CPU Trainer](https://github.com/williamFalcon/pytorch-lightning/blob/master/examples/new_project_templates/trainer_cpu_template.py) 
    - [GPU cluster Trainer](https://github.com/williamFalcon/pytorch-lightning/blob/master/examples/new_project_templates/trainer_gpu_cluster_template.py)
