+# Contributing to Sentrix
+
+Thank you for your interest in contributing! This document describes the
+workflow for proposing changes to Sentrix.
+
+## Code of Conduct
+
+Be respectful and constructive. We're here to improve a security tool, not
+to argue on the internet.
+
+## How to Contribute
+
+### Reporting Issues
+
+- Search existing issues before opening a new one.
+- Include your OS, Rust version (`rustc --version`), and steps to reproduce.
+- For detection pattern improvements, include the exact command line or file
+  content that should be flagged.
+
+### Proposing Changes
+
+1. Open an issue describing the problem or enhancement.
+2. Wait for maintainer feedback before writing code.
+3. Fork the repo and create a feature branch (`git checkout -b my-fix`).
+4. Make your changes, following the style and structure of the existing codebase.
+5. Add tests for any new logic.
+6. Run `cargo fmt`, `cargo clippy`, and `cargo test` before submitting.
+7. Open a pull request with a clear description of the change.
+
+## Development Setup
+
+```bash
+git clone https://github.com/<your-org>/sentrix.git
+cd sentrix
+cargo build
+cargo test
+```
+
+### Prerequisites
+
+- Rust 1.70+ ([install via rustup](https://rustup.rs))
+- For Windows: Administrator terminal for registry access
+- For macOS/Linux: `sudo` may be needed for full visibility
+
+## Project Structure

+```
+
+## Adding a New Check
+
+1. Create `src/scanner/new_check.rs` with a `pub fn run(report: &mut Report)`.
+2. Register it in `src/scanner/mod.rs`: `pub mod new_check;`.
+3. If platform-specific, add implementation in `src/platform/{linux,windows,macos}.rs`.
+4. Call it from `src/main.rs` in the scan sequence.
+5. Add constants to `src/config.rs` if needed.
+6. Write tests in `tests/integration.rs`.
+
+## Adding a New Platform
+
+1. Create `src/platform/newplatform.rs` exporting:
+   - `pub fn check_processes(report: &mut Report)`
+   - `pub fn check_persistence(report: &mut Report)`
+2. Add cfg gate in `src/platform/mod.rs`:
+   ```rust
+   #[cfg(target_os = "newplatform")]
+   mod newplatform;
+   #[cfg(target_os = "newplatform")]
+   pub use newplatform::*;
+   ```
+3. Add platform-specific paths and patterns to `src/config.rs`.
+
+## Style Guide
+
+- Run `cargo fmt` before committing.
+- Run `cargo clippy -- -D warnings` and fix all warnings.
+- Use `snake_case` for functions and variables.
+- Keep functions small and single-purpose.
+- Platform-specific code must live behind `#[cfg(target_os = "...")]` gates.
+- Do not add dependencies unless absolutely necessary.
+
+## Testing
+
+```bash
+cargo test            # run all tests
+cargo test -- --nocapture  # show println! output
+```
+
+Tests live in two places:
+
+- **Unit tests** — co-located in the source file under `#[cfg(test)] mod tests`.
+- **Integration tests** — in `tests/integration.rs`.
+
+When adding a new check, add at least one test that verifies it flags a known
+pattern and does not flag a benign string.
+
+## Pull Request Checklist
+
+- [ ] `cargo fmt` has been run
+- [ ] `cargo clippy -- -D warnings` passes
+- [ ] `cargo test` passes
+- [ ] New logic is covered by tests
+- [ ] README is updated if the change affects usage or configuration
+- [ ] `CHANGELOG.md` is updated (if applicable)

-**Current status:** `tests/integration.rs` exists but is not yet populated.
-Planned test coverage:
-
-- `Report` struct behavior (section, flag, log)
-- Config output (suspicious dirs not empty, constants correct)
-- Scanner edge cases (nonexistent directories, empty files, permission errors)
-- One test per suspicious pattern in `config.rs` to guard against regressions

+tests covering `Report` behavior, config loading (valid, empty, malformed),
+recent-files scanner, pattern constants, and config override flow. Unit tests

 - **No signature scanning** — heuristic only, will miss known malware without suspicious indicators.
 - **No remediation** — reports findings, never removes/quarantines.
 - **No elevated by default** — needs `sudo`/Admin for full visibility.
-- **No CI** — cross-platform compilation is not yet verified by automated testing (see [Roadmap](#roadmap) #1).
-- **No structured output** — plain text only, no JSON/SARIF (see [Roadmap](#roadmap) #5).
-- **Tests not yet implemented** — `tests/integration.rs` is a stub (see [Roadmap](#roadmap) #6).
