+## Usage
+
+To use the model with the `transformers` library on a machine with GPUs:
+
+```
+from transformers import pipeline
+
+instruct_pipeline = pipeline(model="databricks/dolly-v2-12b", trust_remote_code=True, device_map="auto")
+```
+
+You can then use the pipeline to answer instructions:
+
+```
+instruct_pipeline("Explain to me the difference between nuclear fission and fusion.")
+```
+
+To reduce memory usage you can load the model with `bfloat16`:
+
+```
+import torch
+from transformers import pipeline
+
+instruct_pipeline = pipeline(model="databricks/dolly-v2-12b", torch_dtype=torch.bfloat16, trust_remote_code=True, device_map="auto")
+```
