+# Ollama Distribution
+
+The `llamastack/distribution-{{ name }}` distribution consists of the following provider configurations.
+
+{{ providers_table }}
+
+You should use this distribution if you have a regular desktop machine without very powerful GPUs. Of course, if you have powerful GPUs, you can still continue using this distribution since Ollama supports GPU acceleration.
+
+{%- if docker_compose_env_vars %}
+### Environment Variables
+
+The following environment variables can be configured:
+
+{% for var, (default_value, description) in docker_compose_env_vars.items() %}
+- `{{ var }}`: {{ description }} (default: `{{ default_value }}`)
+{% endfor %}
+{% endif %}
+
+{%- if default_models %}
+### Models
+
+The following models are configured by default:
+{% for model in default_models %}
+- `{{ model.model_id }}`
+{% endfor %}
+{% endif %}
+
+## Using Docker Compose
+
+You can use `docker compose` to start a Ollama server and connect with Llama Stack server in a single command.
+
+```bash
+$ cd distributions/{{ name }}; docker compose up
+```
+
+You will see outputs similar to following ---
+```bash
+[ollama]               | [GIN] 2024/10/18 - 21:19:41 | 200 |     226.841µs |             ::1 | GET      "/api/ps"

+[llamastack] |  inner-inference => ollama0

+[llamastack] |  inference => __autorouted__
+```
+
+To kill the server
+```bash
+docker compose down
+```
+
+## Starting Ollama and Llama Stack separately
+
+If you wish to separately spin up a Ollama server, and connect with Llama Stack, you should use the following commands.
+
+#### Start Ollama server
+- Please check the [Ollama Documentation](https://github.com/ollama/ollama) for more details.
+
+**Via Docker**
+```bash
+docker run -d -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama
+```
+
+**Via CLI**
+```bash
+ollama run <model_id>
+```
+
+#### Start Llama Stack server pointing to Ollama server
+
+**Via Conda**
+
+```bash
+llama stack build --template ollama --image-type conda
+llama stack run run.yaml
+```
+
+**Via Docker**
+```
+docker run --network host -it -p 5000:5000 -v ~/.llama:/root/.llama -v ./gpu/run.yaml:/root/llamastack-run-ollama.yaml --gpus=all llamastack/distribution-ollama --yaml_config /root/llamastack-run-ollama.yaml
+```
+
+Make sure in your `run.yaml` file, your inference provider is pointing to the correct Ollama endpoint. E.g.
+```yaml
+inference:
+  - provider_id: ollama0
+    provider_type: remote::ollama
+    config:
+      url: http://127.0.0.1:14343
+```
+
+### (Optional) Update Model Serving Configuration
+
+#### Downloading model via Ollama
+
+You can use ollama for managing model downloads.
+
+```bash
+ollama pull llama3.1:8b-instruct-fp16
+ollama pull llama3.1:70b-instruct-fp16
+```
+
+> [!NOTE]
+> Please check the [OLLAMA_SUPPORTED_MODELS](https://github.com/meta-llama/llama-stack/blob/main/llama_stack/providers.remote/inference/ollama/ollama.py) for the supported Ollama models.
+
+
+To serve a new model with `ollama`
+```bash
+ollama run <model_name>
+```
+
+To make sure that the model is being served correctly, run `ollama ps` to get a list of models being served by ollama.
+```
+$ ollama ps
+
+NAME                         ID              SIZE     PROCESSOR    UNTIL
+llama3.1:8b-instruct-fp16    4aacac419454    17 GB    100% GPU     4 minutes from now
+```
+
+To verify that the model served by ollama is correctly connected to Llama Stack server
+```bash
+$ llama-stack-client models list
++----------------------+----------------------+---------------+-----------------------------------------------+
+| identifier           | llama_model          | provider_id   | metadata                                      |
++======================+======================+===============+===============================================+
+| Llama3.1-8B-Instruct | Llama3.1-8B-Instruct | ollama0       | {'ollama_model': 'llama3.1:8b-instruct-fp16'} |
++----------------------+----------------------+---------------+-----------------------------------------------+
+```
