+`pobsync` is a pull-based backup tool for sysadmins.
 It creates rsync-based snapshots with hardlinking (`--link-dest`) and stores them centrally on a backup server.
 
-Backups are **pulled over SSH**, not pushed, and are designed to be run from cron or manually.

 ## Design overview
 
-- Runtime, config, logs and state live under **`/opt/pobsync`**
-- Backup data itself is stored under a configurable **`backup_root`** (e.g. `/srv/backups`)
-- Two snapshot types:
-  - **scheduled**  
-    Participates in retention pruning (daily / weekly / monthly / yearly)
-  - **manual**  
-    Kept outside the scheduled prune chain, defaults to hardlinking from the latest scheduled snapshot
-- Minimal dependencies (currently only `PyYAML`)

+## Installation (canonical runtime under /opt/pobsync, no venv)
 
 This assumes you are installing as root or via sudo.
 
-From the repository root:
+1) Clone the repo
+
+    git clone https://code.hosting.hippogrief.nl/hippogrief/pobsync.git
+    cd pobsync
+
+2) Deploy the runtime into `/opt/pobsync` (copies code into `/opt/pobsync/lib` and installs `/opt/pobsync/bin/pobsync`)
+
+    sudo ./scripts/deploy --prefix /opt/pobsync
+
+3) Initialize runtime layout and global config
+
+    sudo /opt/pobsync/bin/pobsync install --backup-root /mnt/backups/pobsync
+    sudo /opt/pobsync/bin/pobsync doctor
+
+## Updating
+
+    cd /path/to/pobsync
+    git pull
+    sudo ./scripts/deploy --prefix /opt/pobsync
+    sudo /opt/pobsync/bin/pobsync doctor
