+Online Help
+-----------
+Each {pve} installation contains the full documentation in HTML format,
+which is then used as the target of various help buttons in the GUI.
+
+If after adding a specific entry in the documentation you want to
+create a help button pointing to that, you need to do the
+following:
+
+* add a string id in double square brackets before your 
+documentation entry,  like `[[qm_general_settings]]`
+* rebuild the `asciidoc-pve` script and the HTML chapter file containing 
+your entry
+* add a property `onlineHelp` in the ExtJS panel you want to document,
+using the above string, like `onlineHelp: qm_general_settings`
+This panel has to be a child class of PVE.panel.InputPanel
+
+On calling `make install` the asciidoc-pve script will populate
+a JS object associating the string id and a link to the 
+local HTML documentation, and the help button of your input panel 
+will point to this link.

 First, it should be noted ...

+The corresponding file need to reside inside folder
+`images/screenshot`, and should be in `.png` image format. We include
+the screenshots in printed documentation, and 'pdftex' uses the
+density (DPI) specified inside the file. So all screenshots should use
+the same density. We currently require the density set to 146 DPI, so
+that we can display a 1024 pixels wide image. You should not include
+larger screenshots (although it is possible).
+
+You can use the `./png-cleanup.pl` script to set the correct
+density. Simply use the following command to import a screenshot
+image:
+
+----
+# ./png-cleanup.pl screenshot.png images/screenshot/screenshot.png
+----
+
+TIP: You can use `identify -verbose screenshot.png` command to show
+all image attributes (from debian package 'imagemagick')

+.Default Screenshot Layout
+
+[thumbnail="gui-datacenter-search.png"]
+
+We normally display screenshots as small thumbnail on the right side
+of a paraprah. On printed docomentation, we render the full sized
+graphic just before the paragraph, or between the title and the text
+if the paragraph has a title. It is usually a good idea to add a title
+to paragraph with screenshots.
+
+[thumbnail="gui-datacenter-search.png", float="left"]
+
+If you need to render many screenshots, it is possible to place them
+on the left side, so you can alternate the thumbnail position using the
+`float` attribute:
+
+----
+[thumbnail="gui-datacenter-search.png", float="left"]
+If you need to render many screenshots ...
+----
 
+Please avoid to many consecutive screenshots to avoid rendering
+problems. Also verify the printed documentation to see if large
+screenshots create layout problems.
