 There is no XML decoding and encoding involved, only pure regular expression matching and replacing. So it is much faster than going through decoding and encoding procedures. Moreover, the exact XML source string is preserved, instead of being changed by the encoder. This is why this package exists in the first place. 
 
+Note that 
+
+- the XML is mainly used in Windows environments, thus the default line ending is in Windows' `CRLF` format. To change the default line ending, see the above sample code (first line).
+- the case of XML comments nested within XML comments is ***not*** supported. Please avoid them or use any other tools to correct them before using this package.
+- don't turn on the `nestedTagsInComments` parameter blindly, as the code has become 10+ times more complicated because of it.
