+# Boot SMS
+
+This script uses Free Mobile SMS API to send an SMS informing admin of server reboot.
+
+### Files
+* `boot-sms.sh` is the main script.
+* `wait-reaching.sh` is used by main script to make sure API service is reachable (in practice, delay is the time
+  required by network to be up).
+* `variables.conf.template` contains examples variables definitions, and should be copied locally to `variables.conf`
+  (with any required modifications).
+* `systemd-templates/` contains a Systemd units template for running the script at boot.
+#### Installation
+* `install.sh` script copies the Systemd template to its destination, and enable the service.
+
+### TODO
+* RAS
