+# Challenge61 Multi-Instance Setup Guide
+
+This guide explains how to configure and run Challenge61, which demonstrates how hardcoded Telegram bot credentials can be discovered and exploited. The bot token is double-encoded in base64 to make it slightly more challenging but still discoverable through code inspection.
+
+## Overview
+
+This challenge supports running on multiple app instances (e.g., Arcane and WrongSecrets Heroku apps) using either polling (getUpdates) or webhooks.
+
+## Option 1: Polling with getUpdates (Default - Works Out of Box)
+
+The code uses update offsets to minimize conflicts between multiple app instances:
+- No configuration needed
+- Uses update offsets to minimize conflicts between instances
+- Multiple instances can run simultaneously
+- Less efficient but simpler setup
+- `timeout=0` - No long polling, quick responses
+- `limit=1` - Process one update at a time
+- Offset acknowledgment - Marks updates as processed
+
+**Status**: ✅ Code updated and tested
+
+## Option 2: Webhook Solution (Recommended for Production)
+
+### Step 1: Configure Each Heroku App
+
+For **WrongSecrets Heroku app**:
+```bash
+heroku config:set CHALLENGE61_WEBHOOK_ENABLED=true -a wrongsecrets-app
+heroku config:set CHALLENGE61_WEBHOOK_TOKEN=$(openssl rand -hex 32) -a wrongsecrets-app
+```
+
+For **Arcane Heroku app**:
+```bash
+heroku config:set CHALLENGE61_WEBHOOK_ENABLED=true -a arcane-app
+heroku config:set CHALLENGE61_WEBHOOK_TOKEN=$(openssl rand -hex 32) -a arcane-app
+```
+
+### Step 2: Choose ONE App for the Webhook
+
+You can only set ONE webhook URL per bot. Choose either WrongSecrets or Arcane:
+
+**Option A: Use WrongSecrets app**
+```bash
+# Get your webhook token
+WEBHOOK_TOKEN=$(heroku config:get CHALLENGE61_WEBHOOK_TOKEN -a wrongsecrets-app)
+
+# Set the webhook
+curl -X POST "https://api.telegram.org/bot8132866643:AAHJmvZqvvM9dI2rtBOu--WMZyMFTfHNo9I/setWebhook?url=https://your-wrongsecrets-app.herokuapp.com/telegram/webhook/challenge61&secret_token=$WEBHOOK_TOKEN"
+```
+
+**Option B: Use Arcane app**
+```bash
+# Get your webhook token
+WEBHOOK_TOKEN=$(heroku config:get CHALLENGE61_WEBHOOK_TOKEN -a arcane-app)
+
+# Set the webhook
+curl -X POST "https://api.telegram.org/bot8132866643:AAHJmvZqvvM9dI2rtBOu--WMZyMFTfHNo9I/setWebhook?url=https://your-arcane-app.herokuapp.com/telegram/webhook/challenge61&secret_token=$WEBHOOK_TOKEN"
+```
+
+### Step 3: Verify Webhook
+
+```bash
+curl "https://api.telegram.org/bot8132866643:AAHJmvZqvvM9dI2rtBOu--WMZyMFTfHNo9I/getWebhookInfo"
+```
+
+### Step 4: Test
+
+1. Open @WrongsecretsBot in Telegram
+2. Send `/start`
+3. Bot should respond: "Welcome! Your secret is: telegram_secret_found_in_channel"
+
+## Alternative: Use Both Apps with getUpdates (Current Setup)
+
+If you want both apps to be able to respond (not recommended but possible):
+
+1. **Keep webhook disabled** (default)
+2. **Accept that responses may be inconsistent** - whichever app polls first will respond
+3. **The improved getUpdates code** minimizes conflicts with offset handling
+
+## Troubleshooting
+
+### Check if webhook is active
+```bash
+curl "https://api.telegram.org/bot8132866643:AAHJmvZqvvM9dI2rtBOu--WMZyMFTfHNo9I/getWebhookInfo"
+```
+
+### Remove webhook (to go back to getUpdates)
+```bash
+curl -X POST "https://api.telegram.org/bot8132866643:AAHJmvZqvvM9dI2rtBOu--WMZyMFTfHNo9I/deleteWebhook"
+```
+
+### View Heroku logs
+```bash
+heroku logs --tail -a wrongsecrets-app | grep Challenge61
+heroku logs --tail -a arcane-app | grep Challenge61
+```
+
+## Recommendation
+
+For **production with multiple apps**: Use webhook on ONE primary app (WrongSecrets).
+
+For **development/testing**: The current getUpdates approach with offsets works fine.
+
+## BotFather Configuration (Optional but Recommended)
+
+### 1. Configure Commands
+
+- Send `/setcommands` to @BotFather
+- Select your bot
+- Add: `start - Get the secret message`
+
+### 2. Set Description
+
+- Send `/setdescription` to @BotFather
+- Select your bot
+- Add: "OWASP WrongSecrets Challenge 61 - Demonstrates hardcoded bot credentials. Send /start to receive the secret!"
+
+### 3. Set About Text
+
+- Send `/setabouttext` to @BotFather
+- Add: "Educational security challenge from OWASP WrongSecrets project"
+
+## Testing the Bot
+
+1. Find the bot: Search for @WrongsecretsBot in Telegram (or your bot username)
+2. Send: `/start`
+3. Receive: "Welcome! Your secret is: telegram_secret_found_in_channel"
+
+## Creating a New Bot
+
+If you need to create your own bot for testing:
+
+1. Message @BotFather in Telegram
+2. Send `/newbot`
+3. Follow prompts to choose name and username
+4. BotFather will provide a token like: `1234567890:ABCdefGHIjklMNOpqrsTUVwxyz`
+5. Double-encode the token for use in this challenge:
+   ```bash
+   echo -n "YOUR_TOKEN" | base64 | base64
+   ```
+6. Replace the `encodedToken` value in the `getBotToken()` method in Challenge61.java
