+## Introduction
+
+It is possible to share multiple sessions over a single connection. One of the advantages is that for the duration of the connection, all new sessions open very fast.
+
+## How to
+
+You need a directory to store the sockets for the opened sessions, I use the `~/.ssh/tmp` directory for it. Whatever you choose, make sure it exists by running `mkdir` now. Then add these two lines at the start of your `~/.ssh/config` :
+{{< highlight sh >}}
+ControlMaster auto
+ControlPath   ~/.ssh/tmp/%h_%p_%r
+{{< /highlight >}}
