+Done ✅ — your mirror will now stay up to date automatically. Replace <user> <group> with actual user & group (usually drcit drcit) and any <paths> with the correct *absolute* path (e.g. "/**home/drcit**/.local/logs/aredn.log {")
+
+---
+
+## 🔧 How it works
+1. **Sync**: runs `rsync` to mirror upstream firmware files into `$ROOT`.  
+2. **Patch**: replaces the default firmware URL in `afs/www/config.js` with your local mesh URL (`$NEW_URL`).  
+3. **Collect**: runs `afs/misc/collect.py` to regenerate JSON indexes.  
+4. **Log**: everything is written to `~/.local/logs/aredn.log`.
+
+---
+
+## ⚙️ Variables to Edit
+At the top of `sync.sh`, adjust these for your environment:
+
+```bash
+ROOT="$HOME/<path to root folder>/aredn"  # mirror root
+AFS="$ROOT/afs"                                   # firmware site files
+LOG="$HOME/.local/logs/aredn.log"                 # log path
+UPSTREAM="downloads.arednmesh.org::aredn_firmware" # rsync source
+NEW_URL="http://n2drc-ls1.local.mesh/"           # mesh URL to inject
+```
+
+Replace any <paths> with the correct path (e.g. "$HOME/**docker/fileserver/files**/aredn").
+
+---
+
+## 📅 Cron Job
+To keep your mirror current, run the script daily:
+
+```cron
+0 0 * * * ~/aredn/sync.sh >> ~/.local/logs/aredn.log 2>&1
+```
+
+---
+
+## 📂 Log Rotation
+To prevent logs from growing indefinitely, add `/etc/logrotate.d/aredn-sync`:
+
+```conf
+su <user> <group>
 /home/drcit/.local/logs/aredn.log {
     daily
     rotate 7

+
+This rotates logs daily, keeps 7 days, and compresses older logs. Replace <user> <group> with the actual user & group (usually drcit drcit).
