+# Running on OpenWrt (ARM)
+
+Telbot can run on ARM-based OpenWrt routers to provide a 24/7 Telegram bot or auto-buy monitor.
+
+## Requirements:
+Make sure your are in root user
+```bash
+ssh root@your-router-ip
+```
+
+## 1. Installation
+
+1. SSH into your router and download the ARM binary directly from GitHub:
+   ```bash
+   wget https://github.com/0xtbug/telbot/releases/latest/download/telbot-linux-arm -O /tmp/telbot
+   ```
+2. Move it to `/usr/bin/` and make it executable:
+   ```bash
+   mv /tmp/telbot /usr/bin/telbot
+   chmod +x /usr/bin/telbot
+   ```
+
+## 2. Persistent Configuration
+
+Create .env in /root/ directory
+
+```bash
+# Create .env in /root/ directory
+nano .env
+```
+
+Here is the content of .env
+```bash
+TELKOMSEL_BOT_TOKEN=your_bot_token
+TELEGRAM_ADMIN_ID=your_admin_id
+```
+
+Then copy .env to /.config/telbot/ directory
+```bash
+mkdir -p /.config/telbot/
+
+cp /root/.env /.config/telbot/.env
+
+/etc/init.d/telbot restart
+```
+
+## 3. Run as a Service (procd)
+
+To ensure Telbot starts automatically and restarts on crashes, create a `procd` init script at `/etc/init.d/telbot`:
+
+```bash
+#!/bin/sh /etc/rc.common
+
+USE_PROCD=1
+START=99
+STOP=10
+
+PROG=/usr/bin/telbot
+ENV_FILE=/root/.env
+
+start_service() {
+    [ -f "$ENV_FILE" ] || {
+        echo "❌ File $ENV_FILE tidak ditemukan!"
+        return 1
+    }
+
+    procd_open_instance
+
+    procd_set_param chdir "/root"
+    procd_set_param command "$PROG" --bot --verbose
+
+    while IFS= read -r line || [ -n "$line" ]; do
+        case "$line" in
+            \#*|"") continue ;;
+        esac
+
+        key=$(echo "$line" | cut -d '=' -f 1)
+        val=$(echo "$line" | cut -d '=' -f 2- | tr -d '"' | tr -d "'")
+
+        procd_set_param env "$key"="$val"
+    done < "$ENV_FILE"
+
+    procd_set_param respawn
+    procd_set_param stdout 1
+    procd_set_param stderr 1
+    procd_close_instance
+}
+```
+
+Enable and start the service:
+```bash
+chmod +x /etc/init.d/telbot
+/etc/init.d/telbot enable
+/etc/init.d/telbot start
+```
+
+## 5. Log Monitoring
+
+Check the system logs to see if the bot is running correctly:
+```bash
+logread -f | grep telbot
+```
