Ollama Model File Reference
Ollama can build models automatically by reading the instructions from a Modelfile. A Modelfile is a text document that represents the complete configuration of the Model. You can see that a Modelfile is very similar to a Dockerfile.
Format
Here is the format of the Modelfile:
# comment
INSTRUCTION arguments
Nothing in the file is case-sensitive. However, the convention is for instructions to be uppercase to make it easier to distinguish from the arguments.
A Modelfile can include instructions in any order. But the convention is to start the Modelfile with the FROM instruction.
Although the example above shows a comment starting with a hash character, any instruction that is not recognized is seen as a comment.
FROM
FROM <image>[:<tag>]
This defines the base model to be used. An image can be a known image on the Ollama Hub, or a fully-qualified path to a model file on your system
LICENSE
LICENSE """
<license text>
"""
Some models need to be distributed with a license agreement. For example, the distribution clause for the Llama2 license requires including the license with the model.
PARAMETER
PARAMETER <parameter> <parametervalue>
The PARAMETER instruction defines a parameter that can be set when the model is run.

PROMPT
Prompt is a multiline instruction that defines the prompt to be used when the model is run. Typically there are 3-4 components to a prompt: System, context, user, and response.

### System:
You are a content marketer who needs to come up with a short but succinct tweet. Make sure to include the appropriate hashtags and links.

Every instruction will be the topic to create a tweet about.
