 In addition, you can also create custom variables like [var] or
 arrays like [var1(var2)]. To assign a fixed value to an array
 within the document you can use the notation [var1('value')].
+These variables and their conditions are created from the page
+you can access with the button at the bottom of the document
+editing page.
+Conditions on variables can also be inserted inside the document
+text, so that the part surrounded by the condition is displayed
+only if the condition is satisfied. The format of these
+conditions is:
+[c variable_name="value"]Text under condition[/c]
+where the variable names are written without square
+brackets. The "value" to which the variable is compared
+can be a text surrounded by quotation marks " or another
+variable, in this case without quotation marks. The types of
+comparison can be = (equal), != (not equal), % (text
+included in the first variable), !% (text not included), >
+(greater than) and < (less than). Multiple conditions can be
+joined with & (AND) or | (OR). The conditions are always
+considered as grouped on the right, for example in:
+[c var1="val" & var2!=var3 | var4>"val2" & var5%var6]Text[/c]
+the conditions are grouped as follows:
+var1="val" & (var2!=var3 | (var4>"val2" & var5%var6))
