 ## Setup
 
-Install the files as follows:
+Clone this repository into an arbitrary location `<repo>`. Install the
+executable and APT hook as symlinks so that changes in the checkout are
+immediately available. Install the runtime configuration as a copy so that
+local configuration is not tied to the repository checkout:
 
 ```bash
-sudo install -Dm755 apt-zfs-snapshot.sh /usr/local/sbin/apt-zfs-snapshot
-sudo install -Dm644 apt-zfs-snapshot.conf /etc/apt-zfs-snapshot.conf
-sudo install -Dm644 90apt-zfs-snapshot.conf /etc/apt/apt.conf.d/90apt-zfs-snapshot.conf
+sudo chmod +x <repo>/apt-zfs-snapshot.sh
+sudo ln -s <repo>/apt-zfs-snapshot.sh \
+    /usr/local/sbin/apt-zfs-snapshot
+sudo ln -s <repo>/90apt-zfs-snapshot.conf \
+    /etc/apt/apt.conf.d/90apt-zfs-snapshot.conf
+sudo install -Dm644 <repo>/apt-zfs-snapshot.conf \
+    /etc/apt-zfs-snapshot.conf
 ```
 
+The symlink targets must remain at the paths used in the commands above. If
+you choose different target locations, update the executable path in
+`90apt-zfs-snapshot.conf` as well.
+
 Set `dry_run='true'` in `/etc/apt-zfs-snapshot.conf`, run a harmless APT operation, and inspect the planned names. Set it back to `false` after verifying dataset selection and naming.
 
 The helper runs as root through APT and requires Bash, `zfs`, and `findmnt`.
