+# Podman AI Lab Distribution
+
+```{toctree}
+:maxdepth: 2
+:hidden:
+
+self
+```
+
+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 run_config_env_vars %}
+### Environment Variables
+
+The following environment variables can be configured:
+
+{% for var, (default_value, description) in run_config_env_vars.items() %}
+- `{{ var }}`: {{ description }} (default: `{{ default_value }}`)
+{% endfor %}
+{% endif %}
+
+
+## Setting up Podman AI Lab server
+
+Please check the [Podman AI Lab Documentation](https://github.com/containers/podman-desktop-extension-ai-lab) on how to install and run Ollama. After installing Ollama, you need to run `ollama serve` to start the server.
+
+
+If you are using Llama Stack Safety / Shield APIs, you will also need to pull and run the safety model.
+
+```bash
+export SAFETY_MODEL="meta-llama/Llama-Guard-3-1B"
+
+# ollama names this model differently, and we must use the ollama name when loading the model
+export PODMAN_AI_LAB_SAFETY_MODEL="llama-guard3:1b"
+```
+
+## Running Llama Stack
+
+Now you are ready to run Llama Stack with Podman AI Lab as the inference provider. You can do this via Conda (build code) or Docker which has a pre-built image.
+
+### Via Docker
+
+This method allows you to get started quickly without having to build the distribution code.
+
+```bash
+export LLAMA_STACK_PORT=5001
+docker run \
+  -it \
+  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
+  -v ~/.llama:/root/.llama \
+  llamastack/distribution-{{ name }} \
+  --port $LLAMA_STACK_PORT \
+  --env PODMAN_AI_LAB_URL=http://host.docker.internal:10434
+```
+
+If you are using Llama Stack Safety / Shield APIs, use:
+
+```bash
+# You need a local checkout of llama-stack to run this, get it using
+# git clone https://github.com/meta-llama/llama-stack.git
+cd /path/to/llama-stack
+
+docker run \
+  -it \
+  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
+  -v ~/.llama:/root/.llama \
+  -v ./llama_stack/templates/ollama/run-with-safety.yaml:/root/my-run.yaml \
+  llamastack/distribution-{{ name }} \
+  --yaml-config /root/my-run.yaml \
+  --port $LLAMA_STACK_PORT \
+  --env SAFETY_MODEL=$SAFETY_MODEL \
+  --env PODMAN_AI_LAB_URL=http://host.docker.internal:11434
+```
+
+### Via Conda
+
+Make sure you have done `uv pip install llama-stack` and have the Llama Stack CLI available.
+
+```bash
+export LLAMA_STACK_PORT=5001
+
+llama stack build --template {{ name }} --image-type conda
+llama stack run ./run.yaml \
+  --port $LLAMA_STACK_PORT \
+  --env PODMAN_AI_LAB_URL=http://localhost:10434
+```
+
+If you are using Llama Stack Safety / Shield APIs, use:
+
+```bash
+llama stack run ./run-with-safety.yaml \
+  --port $LLAMA_STACK_PORT \
+  --env SAFETY_MODEL=$SAFETY_MODEL \
+  --env PODMAN_AI_LAB_URL=http://localhost:11434
+```
+
+
+### (Optional) Update Model Serving Configuration
+
+To serve a new model with `Podman AI Lab`:
+- launch Podman Desktop with Podman AI Lab extension installed
+- download the model
+- start an inference server for the model
+
+To make sure that the model is being served correctly, run `curl localhost:10434/api/tags` to get a list of models being served by Podman AI Lab.
+```
+$ curl localhost:10434/api/tags
+{"models":[{"model":"hf.ibm-research.granite-3.2-8b-instruct-GGUF","name":"ibm-research/granite-3.2-8b-instruct-GGUF","digest":"363f0bbc3200b9c9b0ab87efe237d77b1e05bb929d5d7e4b57c1447c911223e8","size":4942859552,"modified_at":"2025-03-17T14:48:32.417Z","details":{}}]}
+```
+
+To verify that the model served by Podman AI Lab is correctly connected to Llama Stack server
+```bash
+$ llama-stack-client models list
+
