 # R_EoM
 
+R_EoM is a library with a demo platform for testing and showcasing its features.
+
+## Project Structure
+
+- `src/lib.rs`: The core library logic.
+- `src/main.rs`: The demo platform application.
+- `tests/`: Integration tests.
+- `flatpak/`: Flatpak manifest for the demo platform.
+
+## Getting Started
+
+### Prerequisites
+
+- Rust and Cargo
+- (Optional) Flatpak and Flatpak Builder
+
+### Building and Running
+
+To build the project:
+
+```bash
+cargo build
+```
+
+To run the demo platform:
+
+```bash
+cargo run --bin r_eom_demo
+```
+
+To run tests:
+
+```bash
+cargo test
+```
+
+### Nix
+
+This project provides Nix support via flakes and a traditional `default.nix`.
+
+To build the project using Nix:
+
+```bash
+nix build
+```
+
+To run the demo platform using Nix:
+
+```bash
+nix run
+```
+
+To enter a development shell:
+
+```bash
+nix develop
+```
+
+(or `nix-shell` for non-flake users)
+
+### Flatpak
+
+To build the Flatpak:
+
+```bash
+make flatpak-build
+```
+
+## IDE Support
+
+### RustRover / IntelliJ Rust
+
+This project includes shared run configurations in the `.run` directory. When you open the project in RustRover or IntelliJ IDEA with the Rust plugin, these configurations will automatically appear in the Run/Debug dropdown:
+
+- **Run Demo**: Executes the `r_eom_demo` binary.
+- **Run Tests**: Executes all tests in the workspace.
+
+Additionally, the IDE automatically detects all targets defined in `Cargo.toml`.
+
+## License

+# Coding Agent Instructions
+
+This project is intended for educational purposes. To support this, please adhere to the following guidelines:
+
+## Allowed Actions
+- **Environment Maintenance:** Feel free to update Nix flakes, shell configurations, or other environment-related setup.
+- **Project Housekeeping:** Maintain a standard project layout, keep `README.md` up-to-date, and clean up temporary or build-related files.
+- **Documentation:** Add comments, manage project documentation, and add links to relevant external resources.
+
+## Restricted Actions
+- **Source Code Editing:** You are NOT allowed to edit the executable source code (`src/` directory) except to improve documentation..
+- **Code Generation:** Do not provide example code unless explicitly asked by the user.
+
+## Communication Guidelines
+- **Educational Focus:** When asked about code, prioritize explaining the concepts and providing advice over writing code.
+- **Documentation Links:** Always include links to official language or library documentation for references.
