+# SendIt: Secure Direct File Sharing
 
-SendIt file-sharing!
\ No newline at end of file
+**SendIt** offers a secure, serverless method to directly share files between users, facilitated by WebSockets. This Python Flask-based application ensures files are transferred peer-to-peer without ever being stored on a server, preserving privacy and reducing dependency on cloud storage.
+
+## Features
+- **Direct Peer-to-Peer Transfers:** Utilizes WebSockets for real-time, direct file sharing without server storage.
+- **Temporary Transfer Codes:** Generates temporary codes for file transfers, which expire after 10 minutes to secure each transaction.
+- **Real-Time Notifications:** Updates senders and receivers about file status, including download progress and time until expiry.
+- **Web Interface:** Simple, intuitive web-based interface for easy file transfers from any modern browser.
+
+## Technologies
+- **Backend:** Python Flask with Flask-SocketIO for handling WebSocket connections.
+- **Frontend:** HTML5, CSS3, and Vanilla JavaScript for a dynamic user experience.
+
+## Installation and Setup
+
+1. **Clone the repository:**
+    ```bash
+    git clone https://github.com/yourusername/SendIt.git
+    cd SendIt/SendIt
+    ```
+
+2. **Install dependencies:**
+    ```bash
+    pip install Flask Flask-SocketIO
+    ```
+
+3. **Run the application:**
+    ```bash
+    python app.py
+    ```
+
+## Usage
+- **Uploading a File:** Drag and drop a file into the web interface or click to select a file. A unique code will be generated.
+- **Downloading a File:** Enter the code received from the sender to begin the direct download.

+    participant Sender
+    participant WebInterface
+    participant Receiver
+
+    Sender->>WebInterface: Starts file upload
+    WebInterface->>Sender: Provide unique code
+    Sender->>Receiver: Share unique code
+    Receiver->>WebInterface: Enter unique code
+    WebInterface->>Sender: Notify file ready for download
+    Sender->>Receiver: Transfer file directly
+    Receiver->>Sender: Notify file received
+    Receiver->>WebInterface: Transfer completed
+
+    Note right of WebInterface: Once file transfer is completed, the connection is closed and resources are cleaned up.
