-## Examples
+## Customize your own model
 
-### Run a model
+### Import from GGUF or GGML
 
-```
-ollama run llama2
->>> hi
-Hello! How can I help you today?
-```
+Ollama supports importing GGUF and GGML file formats in the Modelfile. This means if you have a model that is not in the Ollama library, you can create it, iterate on it, and upload it to the Ollama library to share with others when you are ready.
 
-For multiline input, you can wrap text with `"""`:
+1. Create a file named Modelfile, and add a `FROM` instruction with the local filepath to the model you want to import.
 
-```
->>> """Hello,
-... world!

-I'm a basic program that prints the famous "Hello, world!" message to the console.

-Pull a base model:

+   ollama create name -f path_to_modelfile
+   ```
+
+5. Run the model
+
+   ```

+Models from the Ollama library can be customized with a prompt. The example
 
 ```

+# Installing Ollama on Linux
+
+> Note: A one line installer for Ollama is available by running:
+>
+> ```
+> curl https://ollama.ai/install.sh | sh
+> ```
+
+## Download the `ollama` binary
+
+Ollama is distributed as a self-contained binary. Download it to a directory in your PATH:
+
+```
+sudo curl -L https://ollama.ai/download/ollama-linux-amd64 -o /usr/bin/ollama
+sudo chmod +x /usr/bin/ollama
+```
+
+## Start Ollama
+
+Start Ollama by running `ollama serve`:
+
+```
+ollama serve
+```
+
+Once Ollama is running, run a model in another terminal session:
+
+```
+ollama run llama2
+```
+
+## Install CUDA drivers (optional – for Nvidia GPUs)
+
+[Download and install](https://developer.nvidia.com/cuda-downloads) CUDA.
+
+Verify that the drivers are installed by running the following command, which should print details about your GPU:
+
+```
+nvidia-smi
+```
+
+## Adding Ollama as a startup service (optional)
+
+Create a user for Ollama:
+
+```
+sudo useradd -r -s /bin/false -m -d /usr/share/ollama ollama

+# Sentiments Modelfile
+
+This is a simple sentiments analyzer using the Orca model. When you pull Orca from the registry, it has a Template already defined that looks like this:
+
+```Modelfile
+{{- if .First }}
+### System:
+{{ .System }}
+{{- end }}
+
+### User:
+{{ .Prompt }}
+
+### Response:
+```
+
+If we just wanted to have the text:
+
+```Plaintext
+You are a sentiment analyzer. You will receive text and output only one word, either POSITIVE or NEGATIVE or NEUTRAL, depending on the sentiment of the text.
+```
+
+then we could have put this in a SYSTEM block. But we want to provide examples which require updating the full Template. Any Modelfile you create will inherit all the settings from the source model. But in this example, we are overriding the Template.
+
+When providing examples for the input and output, you should include the way the model usually provides information. Since the Orca model expects a user prompt to appear after ### User: and the response is after ### Response, we should format our examples like that as well. If we were using the Llama 2 model, the format would be a bit different.
