 - **Old Backup Cleanup**: Automatically cleans up old backups on both the Home Assistant server and local machine after a specified retention period.
 - **Notification Support** (Optional): Configure **ntfy** or **Discord** notifications to alert you about the backup status (available in the first script version).
   
-### Three Versions of the Script:
-
-1. **Version 1**  
-   A simpler version that creates a backup, copies it to your local machine, and performs a basic cleanup of old backups locally. No notification system is included in this version.
-
-2. **Version 2**  
-   This version includes backup creation, local and remote cleanup of old backups, and optional notifications via **ntfy** and **Discord**. It also checks for available disk space before cleaning up old backups.
-
-3. **Version 3 (RECOMMENDED)**  
-   This version continues on from 2.0.1 but it has now been ported to Go and has a Go binary

 ## Configuration
 
-Each version has different configuration files
+Go port of `home_assistant_backup.sh`. Uses the same `home_assistant_backup.conf`.
+
+## Build
+    CGO_ENABLED=0 go build -trimpath -ldflags="-s -w" -o ha-backup .
+
+Override the version at build time if needed:
+    CGO_ENABLED=0 go build -trimpath -ldflags="-s -w -X main.version=3.1.2" -o ha-backup .
+
+Check the version:
+    ./ha-backup -version
+
+Cross-compile examples:
+    GOOS=linux GOARCH=amd64 go build -o ha-backup-linux-amd64 .
+    GOOS=linux GOARCH=arm64 go build -o ha-backup-linux-arm64 .   # Raspberry Pi / ARM NAS
+
+
+## Logging
+
+ha-backup writes a log to `/var/log/ha-backup.log` by default. Each line is timestamped, and the file is appended to on every run. The same output is still printed to the console.
+
+### Create the log file
+
+Writing to `/var/log` requires elevated permissions, so create the file once and give ownership to the user that runs the backup. Replace `backupuser` with that user (use `root` if you run it as root):
+
+
+If you'd rather do it in steps:
+
+```
+sudo touch /var/log/ha-backup.log
+sudo chown backupuser:backupuser /var/log/ha-backup.log
+sudo chmod 640 /var/log/ha-backup.log
+```
+
+If the log file can't be opened, ha-backup prints a warning and continues the backup without file logging.
+
+### Change or disable the log location
+
+Set `LOG_FILE` in `home_assistant_backup.conf`:
+
+```bash
+LOG_FILE="/var/log/ha-backup.log"   # default
+LOG_FILE="/home/backupuser/ha-backup.log"   # custom path
+LOG_FILE="none"                     # disable file logging
+```
+
+
+## Run
+    ./ha-backup # looks for home_assistant_backup.conf next to the binary, then in cwd
+    ./ha-backup -config /path/to.conf
+
+
+Requires `ssh` and `scp` on the machine running it. `jq` and `yq` are no longer needed.
+
