+# 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:
+
+```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
+
+```modelfile
+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
+
+## PARAMETER
+
+The PARAMETER instruction defines a parameter that can be set when the model is run. 
+
+```modelfile
+PARAMETER <parameter> <parametervalue>
+```
+
+### Valid Parameters and Values
