# Contributing to Llama-Stack
# Contributing to Llama Stack
We want to make contributing to this project as easy and transparent as
possible.
## Set up your development environment
We use [uv](https://github.com/astral-sh/uv) to manage python dependencies and virtual environments.
You can install `uv` by following this [guide](https://docs.astral.sh/uv/getting-started/installation/).
You can install the dependencies by running:
```bash
cd llama-stack
uv sync --group dev
uv pip install -e .
source .venv/bin/activate
```
```{note}
You can use a specific version of Python with `uv` by adding the `--python <version>` flag (e.g. `--python 3.12`).
Otherwise, `uv` will automatically select a Python version according to the `requires-python` section of the `pyproject.toml`.
For more info, see the [uv docs around Python versions](https://docs.astral.sh/uv/concepts/python-versions/).
```
Note that you can create a dotenv file `.env` that includes necessary environment variables:
```
LLAMA_STACK_BASE_URL=http://localhost:8321
LLAMA_STACK_CLIENT_LOG=debug
LLAMA_STACK_PORT=8321
LLAMA_STACK_CONFIG=<provider-name>
TAVILY_SEARCH_API_KEY=
BRAVE_SEARCH_API_KEY=
```
And then use this dotenv file when running client SDK tests via the following:
```bash
uv run --env-file .env -- pytest -v tests/integration/inference/test_text_inference.py --text-model=meta-llama/Llama-3.1-8B-Instruct
```
### Pre-commit Hooks
We use [pre-commit](https://pre-commit.com/) to run linting and formatting checks on your code. You can install the pre-commit hooks by running:
```bash
uv run pre-commit install
```
After that, pre-commit hooks will run automatically before each commit.
Alternatively, if you don't want to install the pre-commit hooks, you can run the checks manually by running:
```bash
uv run pre-commit run --all-files
```
```{caution}
Before pushing your changes, make sure that the pre-commit hooks have passed successfully.
```
## Discussions -> Issues -> Pull Requests
We actively welcome your pull requests. However, please read the following. This is heavily inspired by [Ghostty](https://github.com/ghostty-org/ghostty/blob/main/CONTRIBUTING.md).
If in doubt, please open a [discussion](https://github.com/meta-llama/llama-stack/discussions); we can always convert that to an issue later.
### Issues
We use GitHub issues to track public bugs. Please ensure your description is
clear and has sufficient instructions to be able to reproduce the issue.
Meta has a [bounty program](http://facebook.com/whitehat/info) for the safe
disclosure of security bugs. In those cases, please go through the process
outlined on that page and do not file a public issue.

## Running tests
You can find the Llama Stack testing documentation [here](https://github.com/meta-llama/llama-stack/blob/main/tests/README.md).
## Adding a new dependency to the project
To add a new dependency to the project, you can use the `uv` command. For example, to add `foo` to the project, you can run:
```bash
uv add foo
uv sync
```
## Coding Style
### Coding Style
* Comments should provide meaningful insights into the code. Avoid filler comments that simply
describe the next step, as they create unnecessary clutter, same goes for docstrings.
