+# Rsync Time Machine
+
+Rsync Time Machine is a backup system, based on rsync and very similar to
+Apple's Time Machine. This means it will keep an history of each file at
+different points in time.
+
+## Pre-requisites
+
+Rsync Time Machine is based on a Client-Server architecture. The clients are
+the workstations to backup. The server is a remote server that will host the
+backups.
+
+Rsync Time Machine is based on rsync, so you will need it on both the
+workstations and the server.
+
+Rsync Time Machine uses SSH to transfer files and authenticate through SSH
+keys, so your server must be reachable through SSH.
