 1. Grab the btrbk binary from the github repo. Copy it to /usr/local/bin/btrbk.
 2. Create a snapshot config
 
-/etc/btrbk/snapshots.conf
+    /etc/btrbk/snapshots.conf
 
-```conf
-snapshot_preserve_min   24h
-snapshot_preserve       14d
+    ```conf
+    snapshot_preserve_min   24h
+    snapshot_preserve       14d
 
-volume /mnt/btr_pools/root
-    subvolume           root
-    snapshot_dir        .snapshots
+    volume /mnt/btr_pools/root
+        subvolume           root
+        snapshot_dir        .snapshots
 
-volume /mnt/btr_pools/root
-    subvolume           home
-    snapshot_dir        .snapshots
+    volume /mnt/btr_pools/root
+        subvolume           home
+        snapshot_dir        .snapshots
 
-volume /mnt/btr_pools/root
-    subvolume           libvirt
-    snapshot_dir        .snapshots
+    volume /mnt/btr_pools/root
+        subvolume           libvirt
+        snapshot_dir        .snapshots
 
-volume /mnt/btr_pools/root
-    subvolume           nextcloud
-    snapshot_dir        .snapshots
-```
+    volume /mnt/btr_pools/root
+        subvolume           nextcloud
+        snapshot_dir        .snapshots
+    ```
 
 3. Then create a snapshot service at /etc/systemd/system/btrbk_snapshots.service
 
-```conf
-[Unit]
-Description=Runs btrbk with config file at /etc/btrbk/snapshots.conf
+    ```conf
+    [Unit]
+    Description=Runs btrbk with config file at /etc/btrbk/snapshots.conf
 
-[Service]
-ExecStart=/usr/local/bin/btrbk -c /etc/btrbk/snapshots.conf -v run
-```
+    [Service]
+    ExecStart=/usr/local/bin/btrbk -c /etc/btrbk/snapshots.conf -v run
+    ```
 
 4. Then create a timer for the service at /etc/systemd/system/btrbk_snapshots.timer
 
-```conf
-[Unit]
-Description=Run snapshots every hour
+    ```conf
+    [Unit]
+    Description=Run snapshots every hour
 
-[Timer]
-OnCalendar=hourly
+    [Timer]
+    OnCalendar=hourly
 
-AccuracySec=10min
-Persistent=true
-Unit=btrbk_snapshots.service
+    AccuracySec=10min
+    Persistent=true
+    Unit=btrbk_snapshots.service
 
-[Install]
-WantedBy=timers.target
-```
+    [Install]
+    WantedBy=timers.target
+    ```
 
 5. Then enable the service
 
-```bash
-systemctl enable --now btrbk_snapshots.conf
+    ```bash
+    systemctl enable --now btrbk_snapshots.conf
+    ```
+
 ```
