+</p>  
+
+Handy library for Telegram/Discord bots development.
+
+## Getting started
+
+There are different sub-packages available:
+
+* pyrogram - Telegram bots with Pyrogram's fork "Pyrofork"
+* pycord - Discord bots with Pycord
+* speed - Performance improvements
+* dev - Dependencies for package development purposes
+
+You can freely choose any sub-package you want, as well as add multiple (comma-separated) or none at all.
+
+```shell
+# Only general features
+pip install libbot
+
+# Only with Pyrogram
+pip install libbot[pyrogram]
+
+# With Pycord and Performance improvements
+pip install libbot[pycord,speed]
+```
+
+## Examples
+
+### Pyrogram
+
+```python
+from libbot.pyrogram import PyroClient
+
+def main():
+    client = PyroClient(scheduler=scheduler)
+
+    try:
+        client.run()
+    except KeyboardInterrupt:
+        print("Shutting down...")
+    finally:
+        if client.scheduler is not None:
+            client.scheduler.shutdown()
+        exit()
+
+
+if __name__ == "__main__":
+    main()
+```
+
+### Pycord
+
+```python
+from discord import Intents
+from libbot import sync
+from libbot.pycord import PycordBot
+
+
+async def main():
+    intents = Intents.default()
+    bot = PycordBot(intents=intents)
+
+    bot.load_extension("cogs")
+
+    try:
+        await bot.start(sync.config_get("bot_token", "bot"))
+    except KeyboardInterrupt:
+        logger.warning("Shutting down...")
+        await bot.close()
+
+
+if __name__ == "__main__":
+    loop = asyncio.get_event_loop()
+    loop.run_until_complete(main())
+```
+
+## Config examples
+
+For bot config examples please check the examples directory. Without a valid config file, the bot won't start at all, so you need to make sure the correct config file is used.
