There are two ways to view `Modelfile`s underlying the models in [ollama.ai/library][1]:
- Option 1: view a details page from a model's tags page:
1. Go to a particular model's tags (e.g. https://ollama.ai/library/llama2/tags)
2. Click on a tag (e.g. https://ollama.ai/library/llama2:13b)
3. Scroll down to "Layers"

- Note: if the [`FROM` instruction](#from-required) is not present,
it means the model was created from a local file
- Option 2: use `ollama show` to print the `Modelfile` like so:

### TEMPLATE
`TEMPLATE` of the full prompt template to be passed into the model. It may include (optionally) a system prompt and a user's prompt. This is used to create a full custom prompt, and syntax may be model specific. You can usually find the template for a given model in the readme for that model.
