+### Formatting
+
+This model was trained on data formatted in the dolly-15k format:
+
+```python
+INSTRUCTION_KEY = "### Instruction:"
+RESPONSE_KEY = "### Response:"
+INTRO_BLURB = "Below is an instruction that describes a task. Write a response that appropriately completes the request."
+PROMPT_FOR_GENERATION_FORMAT = """{intro}
+{instruction_key}
+{instruction}
+{response_key}
+""".format(
+    intro=INTRO_BLURB,
+    instruction_key=INSTRUCTION_KEY,
+    instruction="{instruction}",
+    response_key=RESPONSE_KEY,
+)
+
+example = "James decides to run 3 sprints 3 times a week. He runs 60 meters each sprint. How many total meters does he run a week? Explain before answering."
+fmt_ex = PROMPT_FOR_GENERATION_FORMAT.format(instruction=example)
+```
+
+In the above example, `fmt_ex` is ready to be tokenized and sent through the model.
