 # Frontal web configuration
 
-This repository contains units and config files for our frontal web starting (at boot). We start lighttpd with a WebSSH
-instance running (for web remote access if need be). We must manually unlock certificates volume, then start nginx.
+This repository contains units and config files for our frontal web starting (at boot). Certificates volume should be
+automatically unlocked via TPM. If not, we must manually unlock it and start nginx.
 
 ### Files
 * `etc-letsencrypt.mount` allows to unlock and mount encrypted certificates volume.
   * Relevant information should be added to `/etc/crypttab`.
   * Make sure that `/etc/letsencrypt` directory exists
+* `timeout.conf` is a drop-in Systemd unit file, to let system start even if above volume is not unlocked
 * `wait-for-dns.conf` is a drop-in Systemd unit file, which prevents nginx to start before DNS server is operational.
 #### Installation
 * `install.sh` script copies Systemd files to their destination.
