+# Contributing
+
+Thank you for your interest in contributing to the Salesforce Deployment Failure Analyser.
+
+## Getting Started
+
+```bash
+git clone https://github.com/mssm-sftechstack/salesforce-devops-ai-assistant.git
+cd salesforce-devops-ai-assistant
+pip install pytest
+python -m pytest tests/ -v
+```
+
+No other dependencies are needed to run the tool in mocked mode or to run the tests.
+
+## Ways to Contribute
+
+### Add a new scenario
+Scenarios live in `sample_data/` (input) and `sample_outputs/` (expected output).
+
+1. Create `sample_data/your_scenario.json` following the input schema in the README
+2. Generate output by running: `python main.py --input sample_data/your_scenario.json --live`
+3. Save the result to `sample_outputs/your_scenario_output.json`
+4. Register the scenario in the `SCENARIOS` dict in `main.py`
+
+### Extend the input schema
+- Update `validate_input()` in `main.py` to accept new fields
+- Update `validate_output()` if the output schema changes
+- Add test cases in `tests/test_validation.py`
+- Update the schema table in `README.md`
+
+### Improve the prompt
+The Claude prompt is `CLAUDE_PROMPT` in `main.py`. Changes to the prompt should be validated against all three preset scenarios using `--live` mode before submitting.
+
+### Fix a bug or add a roadmap item
+Open an issue first to describe the change, then submit a pull request referencing the issue.
+
+## Running Tests
+
+```bash
+python -m pytest tests/ -v
+```
+
+All tests must pass before a pull request will be merged.
+
+## Code Style
+
+- Python 3.9+ compatible
+- No external dependencies in the core tool (mocked mode must stay dependency-free)
+- Keep `main.py` self-contained — helper logic belongs in the same file, not a separate module
+
+## Reporting Issues
+
+Open a GitHub issue with:
+- The input JSON you used
+- The error or unexpected output
+- Whether you were using mocked or `--live` mode
