-    <p>Experimental Wayland support. Allows running GNOME Shell and GTK+ applications directly on top of 
Wayland. </p>
-    <p>TO DO: instructions</p>
+    <p>GNOME 3.10 introduces the ability to run a GNOME session and GTK+ applications on top of Wayland. 
This support is still experimental and is primarily intended for testing purposes. If an application fails to 
run on Wayland, it will fall back to X11.</p>
+    <p>To run <code>gnome-shell</code> under Wayland, execute the following command in a terminal:</p>
+    <code>gnome-session --session=gnome-wayland</code>
+    <p>Applications that are launched from a Wayland <code>gnome-shell</code> will also be run in the 
Wayland environment.</p>
+    <p>Alternatively, it is possible to run individual applications on Wayland by specifying the 
<code>GDK_BACKEND</code>. Run the following command, substituting <code>application-name</code> for the 
application's executable name:</p>
+    <code>GDK_BACKEND=wayland application-name</code>
     <p>Further details about GNOME on Wayland can be found on the <link 
href="https://wiki.gnome.org/Wayland";>GNOME Wayland wiki page</link>.</p>

-    <p>TO DO</p>
+    <p>GTK+ 3.10 introduces baseline alignment for text. This allows text labels to be properly vertically 
aligned in relation to containers, which has the added advantage of ensuring consistent text alignment.</p>
+    <p>Base line alignment is available for a range of common widgets. Developers wanting to use it are 
required to set text alignment to baseline. This is done automatically when using helper functions such as 
<code>new_from_label()</code>.</p>
