+<p>
+  Sometimes you will want to save a <dfn>snapshot</dfn> of the current state of a session for possible
+  use in the future. For example, you may be about to change the entire
+  arrangement of a piece, or drastically alter the signal processing, and
+  want a reference to come back to, should that not work out.
+</p>
+<p>
+  This is easily accomplished using <kbd class="menu">Session &gt;
+  Snapshot</kbd>.
+  A small dialog will appear, allowing you to enter a name for the snapshot.
+  The default name is based on the current date and time.<br />
+  You can create any number of snapshots.
+</p>
+<p class="warning">
+  Creating a snapshot does <strong>not</strong> modify your session,
+  nor does it save your session. Instead, it saves an alternate version
+  of the session, within the session folder. The snapshot shares all data
+  present in the session.
+</p>
+<p>
+  After creating a snapshot, you can continue working on the session and
+  save it normally using <kbd class="menu">Session &gt; Save</kbd> and any
+  existing snapshots will remain unchanged.
+</p>
+
+<h2>Switching to a Snapshot</h2>
+<p>
+  If you are already working on a session and want to to switch to an
+  existing snapshot, navigate the  <a href="/ardours-interface/editor-lists/snapshot-list/">Snapshot List</a>.
+  Find the name of the snapshot in the list and click it. Ardour will switch
+  to the snapshot. If there are unsaved changes in the  current session, Ardour will
+  ask what you want to do.
+</p>
+
+<h2>Starting Ardour With a Snapshot</h2>
+<p>
+  Since a snapshot is just another session file stored within the session
+  folder, you can specify that "version" when loading an existing session.
+  The browser in the "Open Session" dialog will show an expander arrow for
+  sessions that have more than 1 session file (i.e. snapshots) present
+  &mdash; click on it to see the list, and then click on the name of the
+  snapshot you want to load.
+</p>
+
+<h2>Saving and Switching to a Snapshot</h2>
+<p>
+  Sometimes you may want to create a snapshot and then have all future
+  edits and modifications saved to that snapshot rather than the main
+  session. This is easily done using <kbd class="menu">Session &gt; Save
+  As</kbd>. This does not create a new session folder,  but saves your
+  session as a new snapshot and then switches the "current snapshot"
+  to the newly created one. All subsequent saves of the session will
+  be stored in this new snapshot, and existing snapshots (and the main
+  session) will be left unaffected.
