+## About the Project
+
+`ft_irc` is an IRC server written mainly in C++. The server supports multiple clients, channels, basic IRC commands, and follows the required features specified in the subject PDF. Its goal is to help understand socket programming, networking concepts, and protocol implementation.
+
+## Getting Started
+
+### Prerequisites
+
+- C++ compiler (tested with C++98/C++11)
+- Make
+- Unix-based OS (Linux/macOS recommended)
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/B-ki/ft_irc.git
+   cd ft_irc
+   ```
+
+2. Build the project:
+   ```bash
+   make
+   ```
+
+### Running the Server
+
+Start the IRC server by specifying the port and password:
+```bash
+./ircserv <port> <password>
+```
+- `<port>`: The port number to listen on (1024-49151 recommended).
+- `<password>`: The password clients need to connect.
+
+### Connecting a Client
+
+You can connect using any IRC client (e.g., irssi, weechat, HexChat):
+```bash
+/server <host> <port> <password>
+```
+
+---
+
+## Usage
+
+Once the server is running, clients can join, create channels, and use standard IRC commands such as `/join`, `/nick`, `/msg`, etc.
+
+---
+
+## Troubleshooting
+
+- **Port already in use**: Make sure the specified port is free or use a different one.
+- **Permission denied**: Use a port above 1024 or run as root (not recommended).
+- **Cannot connect**: Check firewall settings and ensure the server is running.
+- **Build errors**: Ensure your environment supports C++ and Make.
+
+If you encounter other issues, please open an issue on the GitHub repo.

+## Main Developed Functions
+
+Below are some of the main classes and functions you’ll find:
+
+### Server Management
+
+- `Server::start()` — Starts the event loop and listens for new connections.

+- `Server::broadcast()` — Sends messages to all or specific clients/channels.
+
+### Client Management
+
+- `Client::parseCommand()` — Parses and validates client commands.
+- `Client::sendMessage()` — Sends a message to the client.
+
+### Channel Management
+
+- `Channel::addUser()` — Adds a user to a channel.
+- `Channel::removeUser()` — Removes a user from a channel.
+- `Channel::broadcast()` — Sends messages to all users in a channel.
+
+### Command Handling
+
+- `/NICK` — Change user nickname.
+- `/JOIN` — Join a channel.
+- `/PART` — Leave a channel.
