+# Telegram Bot
+
+General-purpose Telegram bot with modular handler architecture.
+
+## Build & Run
+
+```bash
+cargo build --release
+cargo run
+```
+
+## Configuration
+
+Bot token must be placed at: `/var/trust/instagram_link_stripper/telegram_token`
+
+## Architecture
+
+- `src/main.rs` - Entry point, dispatcher setup
+- `src/config.rs` - Token loading from /var/trust/
+- `src/handlers/` - Message handlers (modular, each feature in own file)
+- `src/utils/` - Shared utilities
+
+## Adding New Handlers
+
+1. Create `src/handlers/new_feature.rs`
+2. Export in `src/handlers/mod.rs`
+3. Add handler branch in `handlers::schema()`
+
+## Current Features
+
+### Instagram Link Cleaning (`handlers/instagram.rs`)
+
+Strips tracking parameters from Instagram links:
+- `igsh`, `igshid` - Instagram share tracking
+- `utm_*` - UTM campaign tracking
+- `ref` - Referral tracking
+- `fbclid` - Facebook click ID
+- `si` - Session identifier
