-# Gemini Code Assistant Context
-
-This document provides context for the Gemini code assistant to understand and assist with the development of this project.
-
-## Project Overview
-
-This is a simple, terminal-based Tic-Tac-Toe game written in C++. It uses the `ncurses` library to create the game interface in the terminal. The game is played on a 5x5 grid.
-
-The project is structured into three main components:
-
-*   **`Engine`**: The main game engine that manages the game loop, player turns, and input processing.
-*   **`Window`**: Handles the display of the game board in the terminal.
-*   **`Player`**: Represents a player in the game.
-
-## Building and Running
-
-The project uses CMake for building.
-
-**To build the project:**
-
-```bash
-mkdir build
-cd build
-cmake ..
-make
-```
-
-**To run the game:**
-
-```bash
-./tic_tac_toe
-```
-
-## Development Conventions
-
-*   **Language**: C++23
-*   **Build System**: CMake
-*   **Code Style**: The code follows a consistent style with the use of header guards, and clear naming conventions.
-*   **Testing**: There are no tests in the project.
