+### Кастомизация
+- **Пробник** — Сами решаете будет или нет. Количество дней пробника также кастомизируется.
+- **Реферальная программа** — процент с каждого пополнения или фиксированная сумма.
+- **Все меню** — меняйте все меню как вам захочется, описания и тексты.
+- **Кешбэк** — начисляйте кэшбек за пополнения, если хотите.
+- **Настройки** — капча, подписка на канал, купоны и прочее.
+- **Автоматика** — удалять ли ключи после продления, продлевать ли их и остальное.
 
-Основные технологии, используемые в проекте:
+### *Настраивайте как вам удобно!*
 
-- **Python** версии 3.10 (3.12, для последних версий).
-- **PostgreSQL** — для хранения данных.
-- **aiogram** — для взаимодействия с Telegram API.
-- **aiohttp** — для API запросов к панелям.
 
-Проект полностью асинхронный, что обеспечивает высокую скорость работы.
+## Список версий
 
----
+#### Бот постоянно развивается, обрастая новыми возможностями.
+#### Для полного рассмотрения каждой версии ознакомьтесь с [**релизами**](https://github.com/Vladless/Solo_bot/releases).
 
-## ⚙️ Установка
 
-### 1️⃣ Шаг 1: Клонирование репозитория
-
-Клонируйте репозиторий и перейдите в его директорию:
-
-```bash
-git clone https://github.com/Vladless/Solo_bot.git
-cd solo_bot
-```
-
-### 2️⃣ Шаг 2: Создание и подключение виртуального окружения
-
-Создайте виртуальное окружение **Python** и перейдите в сессию:
-
-```
-python3 -m venv venv
-source venv/bin/activate
-```
-
-### 3️⃣ Шаг 3: Установка зависимостей
-
-Установите зависимости:
-
-```
-pip install -r requirements.txt
-```
-
-### 🛠️ Конфигурация
-
-Для правильной работы вам нужно:
-
-* Установить и запустить **PostgreSQL**, создать пользователя для работы с базой данных и выдать ему права
-* Настроить ваш сервер для работы с ботом, выпустить SSL сертификат для домена
-* Настроить вебхуки и указать пути до них через любой веб-сервер, например **nginx**
-
-* Создать файл config.py в корневой папке проекта с вашими данными:
-
-```
-API_TOKEN = "токен вашего бота телеграм"
-
-ADMIN_USERNAME = "логин от вашей панели x-ray"
-ADMIN_PASSWORD = "пароль от вашей панели x-ray"
-ADD_CLIENT_URL = f"{API_URL}/panel/api/inbounds/addClient"
-GET_INBOUNDS_URL = f"{API_URL}/panel/api/inbounds/list/"
-AUTH_URL = f"{API_URL}/login/"
-```
-
-**Мы высылаем детальный гайд и недостающие файлы в поддержке бота!**
-
-### 🚀 Запуск
-
-Введите команду из виртуального окружения `venv/bin/activate`
