### Interactive Pre-installation Setup

Source: https://context7.com/debotcommunity/debot/llms.txt

Describes the interactive `preinstall` function that prompts users for Telegram API credentials on the first run and saves them encoded in the .env file.

```python
from userbot.src.preinstall import preinstall

# Called automatically if API_ID is not set
# Displays ASCII art "SETUP" banner, then prompts:
# -> [setup] - Введите API ID: <user enters API_ID>
# -> [setup] - Введите API HASH: <user enters API_HASH>

# Creates .env file with encoded credentials:
# API_ID=<base64_encoded_id>
# API_HASH=<base64_encoded_hash>

# Returns tuple: (api_id, api_hash)
api_id, api_hash = preinstall()
```

### Starting the Userbot with Command-Line Arguments

Source: https://context7.com/debotcommunity/debot/llms.txt

Demonstrates how to launch the DeBot userbot from the command line, including options for custom session names, proxy configurations (SOCKS5, HTTP), and authentication.

```bash
# Basic startup with default session name "account"
python3 -m userbot

# Start with custom session file path
python3 -m userbot -s "my_session"

# Start with SOCKS5 proxy (type, ip, port, username, password)
python3 -m userbot -p "socks5" "127.0.0.1" "1080" "user" "pass"

# Combined: custom session with HTTP proxy
python3 -m userbot -s "my_session" -p "http" "192.168.1.1" "8080" "0" "0"
# Note: Use "0" for username/password if proxy has no authentication
```

### Automatic Module Discovery and Import

Source: https://context7.com/debotcommunity/debot/llms.txt

Explains how DeBot automatically discovers and imports all Python modules located in the userbot/modules directory when the userbot starts.

```python
from userbot.modules import ALL_MODULES
```

--------------------------------

### Displaying Available Commands with .help

Source: https://context7.com/debotcommunity/debot/llms.txt

Illustrates how to use the .help command in DeBot to view all registered commands, organized by category such as chat, fun, and tools.

```bash
# In Telegram chat:
# .help

# Output shows registered commands:
# ❓ ᴋ᧐ʍᴀнды:
# ➖ 𝐂𝐡𝐚𝐭
# ➖ 𝐅𝐮𝐧
# ➖ 𝐓𝐨𝐨𝐥𝐬
# .about -> о юзᴇᴩбоᴛᴇ
# .addmod -> добᴀʙиᴛь ʍодуᴧь (ᴩᴇᴨᴧᴀᴇʍ нᴀ ɸᴀйᴧ)
# .delmod -> удᴀᴧиᴛь ʍодуᴧь
```

### Dynamic Module Loading with .addmod Command

Source: https://context7.com/debotcommunity/debot/llms.txt

Explains how to dynamically load a Python module into DeBot by replying to a .py file in Telegram. The module's commands are automatically discovered and registered.

```python
# In Telegram chat:
# 1. Send a .py module file to any chat
# 2. Reply to that file with: .addmod

# Example module structure (mymodule.py):
from telethon import events
from userbot import client

info = {
    "category": "fun",
    "pattern": ".hello|.hi",
    "description": "Says hello|Says hi"
}

@client.on(events.NewMessage(outgoing=True, pattern=r"^\.hello$"))
async def hello_handler(event):
    await event.edit("Hello, World!")

@client.on(events.NewMessage(outgoing=True, pattern=r"^\.hi$"))
async def hi_handler(event):
    await event.edit("Hi there!")
```

### Encoding and Decoding Credentials with CryptoUtils

Source: https://context7.com/debotcommunity/debot/llms.txt

Shows how the CryptoUtils class in DeBot uses base64 encoding and decoding for API credentials stored in the .env file, ensuring secure storage.

```python
from userbot.src.encrypt import CryptoUtils

# Encode credentials for storage
api_id = "12345678"
encoded_id = CryptoUtils.encrypt(api_id)
# Result: "MTIzNDU2Nzg="

# Decode credentials on load
decoded_id = CryptoUtils.decrypt(encoded_id)
# Result: "12345678"

# Used automatically by preinstall() to save credentials:
# .env file contents:
# API_ID=MTIzNDU2Nzg=
# API_HASH=YWJjZGVmMTIzNDU2...
```

--------------------------------

### Module Uninstallation with .delmod Command

Source: https://context7.com/debotcommunity/debot/llms.txt

Details the process of removing a DeBot module using the .delmod command, which includes deleting the module file, cleaning up event handlers, and removing it from sys.modules.

```bash
# In Telegram chat, delete a module by name:
# .delmod mymodule

# The command will:
# 1. Delete the file from userbot/modules/
# 2. Remove all registered event handlers for that module
# 3. Clean up sys.modules entries
# Console output: "-> [.delmod] - Модуль mymodule успешно удален"
```

--------------------------------

### TelegramClient Extension for HTML and Session Protection

Source: https://context7.com/debotcommunity/debot/llms.txt

Shows how the extended TelegramClient in DeBot defaults to HTML parse mode for messages and includes protection against unauthorized session string extraction.

```python
from userbot import client

# The client is pre-configured and ready to use
# HTML is the default parse mode for all messages

# Send a message with HTML formatting
await client.send_message(
    "me",
    "<b>Bold</b> and <i>italic</i> text"
)

# The client includes session grab protection
# Any attempt to call client.save() raises RuntimeError:
# "Save string session try detected and stopped. Check external libraries."
```
