-
-**Supported Formatting:**
-- **Bold text**: Use `*text*` (single asterisk, not double asterisks)
-- **Italic text**: Use `_text_` (underscore)
-- **Code**: Use `` `text` `` (backtick)
-- **Links**: Use `[text](url)` format
-- **Strikethrough**: Use `~text~` (tilde)
-
-**IMPORTANT - Headings and Lists:**
-- **DO NOT use heading syntax** (`#`, `##`, `###`) - Telegram MarkdownV2 does NOT support it
-- **Instead, use bold text for headings**: `*Heading Text*` followed by a blank line
-- **DO NOT use list syntax** (`-`, `*`, `+` at line start) - these will be escaped and won't display as lists
-- **For lists**, use plain text with line breaks, or use bold for list item labels: `*Item 1:* description`
-
-**Examples:**
-- ❌ Wrong heading: `# Main Title` or `## Subtitle`
-- ✅ Correct heading: `*Main Title*` (followed by blank line) or `*Subtitle*` (followed by blank line)
-- ❌ Wrong list: `- Item 1` or `* Item 2`
-- ✅ Correct list format: `*Item 1:* description` or use plain text with line breaks
-
-**Special Characters:**
-- Avoid using special characters that need escaping in MarkdownV2: `_*[]()~`>#+-=|{}.!` unless they are part of the formatting syntax
-- Keep formatting simple, avoid nested formatting to ensure proper rendering in Telegram"""
