• note the document tree on the left side bar of the Portal. The tree is designed to help you find your way to the right document. If you won't see the tree then it's most likely turned off. That' easy to fix - just look on the top-right side of this page and notice a little icon (left to the 'Search' box) which will toggle the visibility of the side bar.
• most pages in this site list topics to review next, as well as additional related topics
• feel free to use search on the sidebar just above the tree. Please do so only if you know what you're looking for. In other cases a better approach would be to use the tree structure to get yourself familiar with the general structure of the documentation. This may make your search more efficient.
• some pages on this site will redirect you (if needed) to other Confluence 'spaces' (sites). Note that the 'Search' will not propagate to those other spaces
• for those who're impatient enough to "get the right answer" quicker we have also prepared the usual HOWTO which is found in the very end of the document tree. If you think there is something important missing on the HOWTO list then let us know please. You may contact us as explained at the bottom of this page.
