+# APT autoremove
+
+The purpose is to run `apt-get autoremove` regularly on systems. Main use-case is to remove old kernels on Ubuntu-based
+systems, to free space in `/boot`.
+
+### Files
+* `systemd-templates/` contains Systemd units templates for running the the command unattended.
+#### Installation
+* `install.sh` script copies Systemd templates to their destination, and enables timer.
+
+### TODO
+* RAS

install.sh
