+# Treender
 
-# Code style
+A genetic algorithm visualization tool with interactive evolution simulation.
 
-## Naming Conventions:
-- PascalCase: 
-  - Functions
-  - Class names
-  - Struct names
+## Overview
 
-- camelCase: 
-  - Class attributes
-  - Class methods
-  - Struct attributes
-  - Variables
+Treender is a C++ application that simulates genetic algorithms through an interactive visual interface. Users can observe and influence the evolution of digital organisms represented as visual patterns.
 
-## Class Structure:
+## Features
 
-- Header (.h) Files:
-  - Declare public methods and attributes first, followed by private members.
-- Implementation (.cpp) Files:
-  - Implement methods in the same order as declared in the corresponding header file.
+- **Interactive Evolution**: Like/dislike organisms to guide evolution
+- **Genetic Algorithm**: DNA-based reproduction with mutation
+- **Visual Representation**: Organisms displayed as colorful patterns
+- **Client-Server Architecture**: Separate app and server components
+- **Cross-Platform**: Supports Web, Android, and Desktop platforms
 
-## Include order
-  - Std
-  - local ( form inc dir )
-  - external raylib

+Treender
+├── app/          # Main application (Raylib + Dear ImGui)
+├── server/       # TCP server for data management
+├── shared/       # Shared code (DNA logic, networking)
+├── external/      # Third-party libraries
+└── data.db       # SQLite database
+```
+
+## Components
+
+### Application
+- **Main Entry**: `app/src/main.cpp`
+- **Core Class**: `App` class handles rendering, input, and evolution logic
+- **Visualization**: Uses Raylib for graphics and Dear ImGui for UI
+
+### Server
+- **TCP Server**: Handles client connections and data persistence
+- **Database**: SQLite for storing organism data and user preferences
+- **Block Management**: Tracks warnings and blocked organisms
+
+### Shared Library
+- **DNA System**: Genetic algorithm implementation (`Dna.cpp`)
+- **Networking**: TCP socket communication
+- **Data Structures**: Shared between app and server
+
+## Building
+
+### Prerequisites
+- CMake 3.10+
+- C++17 compiler
+- Raylib
+- Dear ImGui
+- SQLite3
+
+### Build Instructions
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+## Running
+
+1. Start the server:
+```bash
+./build/server
+```
+
+2. Run the application:
+```bash
+./build/app
+```
+
+## Usage
+
+- **Like/Disike**: Click on organisms to influence evolution
+- **Rotation**: Drag to rotate the view
+- **Statistics**: View similarity scores and generation information
+
+## Database
+
+The application uses SQLite database (`data.db`) to store:
+- Organism DNA data
+- User preferences
+- Blocked/warned organisms
