+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.

+.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.
