 # Ollama
 
-Run large language models with `llama.cpp`.
+Create, run, and share self-contained large language models (LLMs). Ollama bundles a model’s weights, configuration, prompts, and more into self-contained packages that run anywhere.
 
-> Note: certain models that can be run with Ollama are intended for research and/or non-commercial use only.
+> Note: Ollama is in early preview. Please report any issues you find.
 
-### Features
+## Download
 
-- Download and run popular large language models
-- Switch between multiple models on the fly
-- Hardware acceleration where available (Metal, CUDA)
-- Fast inference server written in Go, powered by [llama.cpp](https://github.com/ggerganov/llama.cpp)
-- REST API to use with your application (python, typescript SDKs coming soon)
+- [Download](https://ollama.ai/download) for macOS on Apple Silicon (Intel coming soon)
+- Download for Windows and Linux (coming soon)
+- Build [from source](#building)
 
-## Install
+## Examples
 
-- [Download](https://ollama.ai/download) for macOS with Apple Silicon (Intel coming soon)
-- Download for Windows (coming soon)
-
-You can also build the [binary from source](#building).
-
-## Quickstart
-
-Run a fast and simple model.
+### Quickstart
 
 ```
-ollama run orca
+ollama run llama2
+>>> hi
+Hello! How can I help you today?
 ```
 
-## Example models
+### Creating a custom model
 
-### 💬 Chat
-
-Have a conversation.
+Create a `Modelfile`:
 
 ```
-ollama run vicuna "Why is the sky blue?"
+FROM llama2
+PROMPT """
+You are Mario from Super Mario Bros. Answer as Mario, the assistant, only.
+
+User: {{ .Prompt }}
+Mario:
+"""
 ```
 
-### 🗺️ Instructions
-
-Get a helping hand.
+Next, create and run the model:
 
 ```
-ollama run orca "Write an email to my boss."
+ollama create mario -f ./Modelfile
+ollama run mario
+>>> hi
+Hello! It's your friend Mario.
 ```
 
-### 🔎 Ask questions about documents
+## Model library
 
-Send the contents of a document and ask questions about it.
+Ollama includes a library of open-source, pre-trained models. More models are coming soon. You should have at least 8 GB of RAM to run the 3B models, 16 GB
+to run the 7B models, and 32 GB to run the 13B models.

+# 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>
+```
