         <p>This set up is designed to allow you to project/share cases in a seperate window whilst controlling/tracking their display from this page.</p>
-        <p>Click on the 'Load' button to open the case in a new window/tab, this should be positioned on it's own window (you may have to detach the tab). Opening subsequent cases/series will replace the first case in the window.</p>
-        <p>It is also possible to open a single series by clicking on the 'Load' button next to the indvidual series.</p>
+        <p>First you will need to open the linked viewer window by clicking the 'Open Viewer' button. This will open a new window/tab with the viewer in it. You will probably need to detach this from your current window.</p>
+        <p>If you are sharing the window you can maximise the screen area by hiding the tab/bookmark bar and the address bar. In Microsoft Edge this can be done by installing as an app, in Chrome you can use an extension such as <a href='https://chromewebstore.google.com/detail/ncppfjladdkdaemaghochfikpmghbcpc'>Open-as-Popup</a>.</p>

+        <p>It is also possible to open a single series by clicking on the 'Load' button next to the individual series.</p>
         <p>Once opened the case details will be show on the right hand side of the page.</p>
