+# Linux Voice Assistant - AI Policy
+
+We support using AI (i.e., LLMs) as tools when contributing to Linux Voice Assistant. However, you are responsible for any contributions you submit, and we are responsible for any contributions we merge and release. We hold a high bar for all contributions to our projects.
+
+Our maintainers dedicate their time and expertise to reviewing contributions. Submitting AI-generated content that you have not personally reviewed and understood wastes that time and will not be accepted.
+
+## Autonomous agents
+
+We do not allow autonomous agents to be used for contributing to our projects. We will close any pull requests or issues that we believe were created autonomously, and may mark automated comments as spam. This includes contributions that bypass the provided issue or pull request templates.
+
+## Communication on issues, pull requests, and code reviews
+
+We don't mind if you use AI tools to help you write. However, do not have tools post unreviewed content on your behalf. Keep responses to the minimum needed to communicate your intent. We may hide any comments that we believe are unreviewed AI output.
+
+If you are opening a pull request, we expect you to be able to explain the proposed changes in your own words. This includes the pull request description and responses to questions. If you use AI to help generate the pull request summary, you must review it for technical accuracy.
+
+**Do not use AI to generate answers to questions from maintainers.** You should understand and be able to explain your own work. Using AI to improve grammar or clarity is fine, but the substance of your responses must be your own.
+
+If you wish to include context from an interaction with AI in your comments, it must be in a quote block (e.g., using `>`) and disclosed as such. It must be accompanied by your own commentary explaining the relevance and implications of the context. Do not share long snippets.
+
+## Non-native English speakers
+
+We understand that AI is useful when communicating as a non-native English speaker. If you are using AI to translate your comments, please ensure the translation accurately reflects your intent. Including your original text in a details block shows the effort behind your contribution, helps maintainers verify the translation if needed, and keeps the conversation readable.
+
+## Code and documentation contributions
+
+AI can be a helpful tool for writing code and documentation. However, due to the foundational open source nature of our projects, we require a human in the loop who understands the work produced by AI.
+
+All contributions must be reviewed and understood by the contributor before submission. You should be able to explain every change in a pull request you submit. Pull requests that appear to be unreviewed AI output will be closed without review.
+
+## Our use of AI
+
+Some of our projects use AI tools to assist with code reviews, issue triaging, reporting, and other project management tasks. These tools may leave comments on pull requests or issues. As with any automated tooling, these comments are not always correct.
+
+If an AI tool leaves a comment on your contribution, treat it as you would any other review comment. If you believe it is incorrect, say so; a brief explanation is sufficient. Maintainers always have the final say. If in doubt, ask a maintainer.
+
+## Enforcement
+
+Contributions that do not follow this policy will be closed. Repeated violations may result in being blocked from contributing to LVA projects.

+# Contributing to Linux Voice Assistant
+
+Everybody is invited and welcome to contribute to Linux Voice Assistant. Even if you are not a developer, perhaps you would like to help with the documentation? If you are a developer and have a feature that isn't supported by LVA yet, why not spend some time and help to integrate it?
+
+The process is straight-forward.
+
+- Fork the LVA repository.
+- Write the code for your feature or fix.
+- Ensure tests pass and linting succeeds (`./script/lint` and `./script/tests`).
+- Create a Pull Request against the `main` branch.
+
+## Feature suggestions
+
+If you want to suggest a new feature for LVA, please open a discussion on GitHub.
+
+## Issue Tracker
+
+If you want to report an issue, please create an issue on the repository.
+
+## AI Policy
+
+Linux Voice Assistant is an [Open Home Foundation](https://www.openhomefoundation.org/) project and follows the [OHF AI Policy](https://github.com/music-assistant/.github/blob/main/AI_POLICY.md). Please read it before submitting AI-assisted contributions. The TLDR: AI tools are allowed, but a human is responsible and must review and understand every change. Autonomous agents and unreviewed AI output will be rejected.

+**Python:**
+- Python 3.11+ must be installed on your system (`python3 --version` should show 3.11+)
+- On Ubuntu/Debian: `sudo apt install python3.11 python3.11-venv python3.11-dev`
+
+### VS Code Setup
+
+VS Code development uses a local Python virtual environment (`.venv/`):
+
+1. Open workspace in VS Code
+2. Accept Workspace Trust (bottom-left status bar)
+3. Install recommended extensions when prompted:
+   - `ms-python.python` - Python language support
+   - `ms-python.vscode-pylance` - Python language server
+   - `kilo.kilocode` - Kilo AI assistant
+4. **Terminal** → **New Terminal** (or `` Ctrl+` ``) - Opens integrated terminal (uses .venv when available)
+5. Run `./script/setup --dev` to create `.venv` and install dev dependencies
+6. VS Code automatically detects `.venv/bin/python` as the Python interpreter
+
+**Available VS Code Tasks:**
+- `Ctrl+Shift+B` - Run Setup or Linter
+- `Ctrl+Shift+T` - Run Tests
+- `Ctrl+Shift+P` → "Tasks: Run Task" - Show all tasks (Setup, Linter, Tests, Run App)
+
