 ### Obtain alignment information
 
+Alignment is returned as a string value of the following format for every word of the source. The information for each word is separated by a space, including for non-space-separated languages (scripts) like Chinese:
+
+[[SourceTextStartIndex]:[SourceTextEndIndex]–[TgtTextStartIndex]:[TgtTextEndIndex]] *
+
+Example alignment string: "0:0-7:10 1:2-11:20 3:4-0:3 3:4-4:6 5:5-21:21".
+
+In other words, the colon separates start and end index, the dash separates the languages, and space separates the words. One word may align with zero, one, or multiple words in the other language, and the aligned words may be non-contiguous. When no alignment information is available, the Alignment element will be empty. The method returns no error in that case.
+
 To receive alignment information, specify `includeAlignment=true` on the query string.
