+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `main/` holds the application entry point (`main.c`) and its build file (`main/CMakeLists.txt`).
+- `components/stepper_motor/` contains the reusable stepper motor component. Public headers live in `components/stepper_motor/include/` and source in `components/stepper_motor/stepper_motor.c`.
+- `build/` is generated by ESP-IDF/CMake; do not edit or commit build artifacts.
+- `sdkconfig` is the project configuration used by ESP-IDF; `sdkconfig.old` is a backup after config changes.
+
+## Build, Test, and Development Commands
+Run these from an ESP-IDF environment with `IDF_PATH` set:
+- `idf.py build` — configure and compile the firmware into `build/`.
+- `idf.py flash -p <PORT>` — flash to the connected device.
+- `idf.py monitor` — open the serial monitor.
+- `idf.py flash monitor -p <PORT>` — common flash + monitor workflow.
+- `idf.py menuconfig` — edit `sdkconfig` interactively.
+- `idf.py fullclean` — remove build output and cached configuration.
+
+## Coding Style & Naming Conventions
+- C code uses 4-space indentation with braces on the same line.
+- Use `lower_snake_case` for functions/variables, `UPPER_SNAKE_CASE` for macros, and `*_t` suffixes for typedefs.
+- Prefer `static` for file-local helpers and use `ESP_LOGx` for logging.
+- Keep component APIs in `components/<name>/include/` and include with quotes (e.g., `"stepper_motor.h"`).
+
+## Testing Guidelines
+- No automated test framework is configured in this repo.
+- Validate behavior on hardware after changes; include manual test steps and results in PR descriptions.
+
+## Commit & Pull Request Guidelines
+- Git history shows short, imperative summaries without scopes (e.g., "Initial commit").
+- PRs should include: a short description, hardware/board tested, and any notable serial output or behavior changes. Attach photos/videos when motion behavior changes.
+
+## Configuration & Hardware Notes
+- GPIO assignments and motion parameters are defined in `components/stepper_motor/include/stepper_motor.h`.
+- Update pin mappings and timing constants there if wiring or motor characteristics change.
