# Contributing to Ollama

Thank you for your interest in contributing to Ollama! Here are a few guidelines to help get you started.

## Set up

See the [development documentation](./docs/development.md) for instructions on how to build and run Ollama locally.

### Ideal issues

* [Bugs](https://github.com/ollama/ollama/issues?q=is%3Aissue+is%3Aopen+label%3Abug): issues where Ollama stops working or where it results in an unexpected error.
* [Performance](https://github.com/ollama/ollama/issues?q=is%3Aissue+is%3Aopen+label%3Aperformance): issues to make Ollama faster at model inference, downloading or uploading.
* [Security](https://github.com/ollama/ollama/blob/main/SECURITY.md): issues that could lead to a security vulnerability. As mentioned in [SECURITY.md](https://github.com/ollama/ollama/blob/main/SECURITY.md), please do not disclose security vulnerabilities publicly.

### Issues that are harder to review

* New features: new features (e.g. API fields, environment variables) add surface area to Ollama and make it harder to maintain in the long run as they cannot be removed without potentially breaking users in the future.
* Refactoring: large code improvements are important, but can be harder or take longer to review and merge.
* Documentation: small updates to fill in or correct missing documentation is helpful, however large documentation additions can be hard to maintain over time.

### Issues that may not be accepted

* Changes that break backwards compatibility in Ollama's API (including the OpenAI-compatible API)
* Changes that add significant friction to the user experience
* Changes that create a large future maintenance burden for maintainers and contributors

## Proposing a (non-trivial) change

> By "non-trivial", we mean a change that is not a bug fix or small
> documentation update. If you are unsure, please ask us on our [Discord
> server](https://discord.gg/ollama).

Before opening a non-trivial Pull Request, please open an issue to discuss the change and
get feedback from the maintainers. This helps us understand the context of the
change and how it fits into Ollama's roadmap and prevents us from duplicating
work or you from spending time on a change that we may not be able to accept.

Tips for proposals:

* Explain the problem you are trying to solve, not what you are trying to do.
* Explain why the change is important.
* Explain how the change will be used.
* Explain how the change will be tested.

Additionally, for bonus points: Provide draft documentation you would expect to
see if the change were accepted.

## Pull requests

**Commit messages**

The title should look like:

   <package>: <short description>

The package is the most affected Go package. If the change does not affect Go
code, then use the directory name instead. Changes to a single well-known
file in the root directory may use the file name.

The short description should start with a lowercase letter and be a
continuation of the sentence:

      "This changes Ollama to..."

Examples:

      llm/backend/mlx: support the llama architecture
      CONTRIBUTING: provide clairity on good commit messages, and bad

Bad Examples:

      feat: add more emoji
      fix: was not using famous web framework
      chore: generify code

**Tests**

Please include tests. Strive to test behavior, not implementation.

**New dependencies**

Dependencies should be added sparingly. If you are adding a new dependency,
please explain why it is necessary and what other ways you attempted that
did not work without it.
