+SSH launcher which saves a history of launched sessions which can be filtered through using auto completion and keyboard navigation the next time you want to launch a session.
+
+## Usage
+
+### Launch a new session
+Run `launch_ssh` from the menu (or a global keyboard shortcut to be extra quick) and type which host you want to connect to.
+
+Press `RETURN` to start the session in a new terminal.
+
+This saves the session hostname in your history and will make it easy to start the next time.
+
+
+### Navigate and autocomplete
+When some history items are filled in, you can navigate quickly through them using the arrow and `RETURN` keys or by typing some letters and pressing `TAB` for auto completion.
+
+### Delete old sessions
+Delete records from your history you don't want using the `DELETE` key.
