+# Copilot Instructions
+
+## Python Environment
+
+Always activate and use the Python virtual environment when running Python commands:
+
+- On Windows: `.venv\Scripts\activate`
+- On Linux/macOS: `source .venv/bin/activate`
+
+Use `python -m pip` instead of bare `pip` when installing packages.
+
+## Dev Setup
+
+Install all dependencies with:
+
+```
+python -m pip install -e ".[dev,test]"
+```
+
+## Python Version
+
+This project requires Python 3.10 or newer.
+
+## Project Structure
+
+- `featuremanagement/` — Synchronous feature management code
+- `featuremanagement/aio/` — Async equivalents of feature management classes
+- `featuremanagement/_models/` — Data models (feature flags, variants, telemetry)
+- `featuremanagement/_time_window_filter/` — Time window filter with recurrence support
+- `featuremanagement/azuremonitor/` — Optional Azure Monitor telemetry integration
+- `tests/` — Unit tests (sync and async)
+- `samples/` — Sample applications
+
+## Code Conventions
+
+- All source files must include the Microsoft copyright header.
+- All modules must have a module-level docstring.
+- Maximum line length is 120 characters.
+- Use type annotations on all functions and methods.
+
+## Code Quality
+
+Run these before submitting changes:
+
+```
+black featuremanagement
+pylint featuremanagement
+mypy featuremanagement
+pytest tests
+```
+
+## Testing
+
+- Sync tests are in `tests/test_*.py`
+- Async tests use `pytest-asyncio` and are in files ending with `_async.py`
+- Run tests with: `pytest tests`
