+# Simple NPMplus Update Instructions
+
+**Target**: Update to `zoeyvid/npmplus:2026-01-20-r2`
+
+---
+
+## Quick Update (Run on r630-01)
+
+```bash
+# SSH to Proxmox host
+ssh root@192.168.11.10
+ssh root@r630-01
+
+# Run these commands:
+pct exec 10233 -- docker pull zoeyvid/npmplus:2026-01-20-r2
+pct exec 10233 -- docker stop npmplus
+pct exec 10233 -- docker rm npmplus
+pct exec 10233 -- docker run -d \
+  --name npmplus \
+  --restart unless-stopped \
+  --network bridge \
+  -p 80:80 \
+  -p 443:443 \
+  -p 81:81 \
+  -v /data/npmplus:/data \
+  -v /data/letsencrypt:/etc/letsencrypt \
+  zoeyvid/npmplus:2026-01-20-r2
+
+# Verify
+pct exec 10233 -- docker ps --filter name=npmplus
+curl -I http://192.168.11.167:80
+```
+
+---
+
+## If Network Timeout During Pull
+
+The Docker pull may timeout due to network issues. In that case:
+
+1. **Wait for container creation** - Docker will pull the image automatically when creating the container
+2. **Or pull manually later** - The container will work with `latest` tag, then you can pull the specific version later
+
+---
+
+## Verification
+
+After update:
+
+```bash
+# Check version
+pct exec 10233 -- docker inspect npmplus --format '{{.Config.Image}}'
+
+# Test accessibility
+curl -I http://192.168.11.167:80
+curl -I https://192.168.11.167:81 -k
+
+# Test proxy
+curl -H "Host: explorer.d-bis.org" http://192.168.11.167:80
+```
