+# FIX Repository Wiki
+
+## Home
+### Welcome to the FIX Repository Wiki!
+The **FIX Repository** is a terminal-based client designed to implement and interact with the **REChain Basis Protocol**, a decentralized communication and blockchain protocol. The client offers cross-platform compatibility, high security, and efficiency, leveraging Rust and Cargo for robust terminal-based functionality.
+
+---
+
+## Getting Started
+### Prerequisites
+- Rust (latest stable version)
+- Cargo (Rust's package manager)
+- Terminal or shell environment (Linux, macOS, or Windows with PowerShell or WSL)
+
+### Installation
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/sorydima/FIX.git
+   cd FIX
+   ```
+2. Build the project:
+   ```bash
+   cargo build --release
+   ```
+3. Run the client:
+   ```bash
+   cargo run
+   ```
+
+### Configuration
+- The configuration file `config.toml` must include:
+  ```toml
+  [network]
+  node_address = "127.0.0.1:8080"
+  federation_mode = true
+
+  [encryption]
+  enable_e2e = true
+  ```
+- Adjust the settings to connect to your REChain Basis node or local server.
+
+---
+
+## Features
+1. **Cross-Platform Support**  
+   Run seamlessly on Linux, macOS, and Windows.
+
+2. **Real-Time Messaging**  
+   Supports chat, group messaging, and federated communication between servers.
+
+3. **End-to-End Encryption**  
+   Secure communication with E2EE for maximum privacy.
+
+4. **Decentralized Federation**  
+   Connect to REChain Basis servers and interact with the broader network.
+
+5. **Modular Design**  
+   Expandable with additional modules for file sharing, video calls, and more.
+
+---
+
+## Architecture
+### Protocol Overview
+The FIX client implements core features of the **REChain Basis Protocol**, including:
+- **Federation:** Servers exchange data securely and efficiently.
+- **Messaging API:** REST and WebSocket interfaces for seamless communication.
+- **Data Synchronization:** Supports backfill and re-sync for robust message delivery.

+## Usage Guide
+### Basic Commands
+- **Login:**
+  ```bash
+  fix-cli login --username "user" --password "password"
+  ```
+- **Send Message:**
+  ```bash
+  fix-cli send --to "room_id" --message "Hello, REChain!"
+  ```
+- **Retrieve Messages:**
+  ```bash
+  fix-cli fetch --room "room_id"
+  ```
+
+### Advanced Configuration
+- **Federation Mode:**
+  Enable `federation_mode` in `config.toml` for decentralized communication.
+- **Offline Mode:**
+  Allows autonomous operation without an internet connection.
