+#I know that this issue is closed, but as I spent a lot of time to understand what was going on, I made some researches and I can explain why this happen, and you can fix it.
+#
+#Using git config core.autocrlf true can help, but not on a multi-developpers project.
+#This command has to be the same on each developper machine, and that's not always the case.
+#
+#You have to use the .gitattributes provided in the puphpet archive and edit it as follow (carefull, this file need to be in your project root)
+#You also need to use an IDE that allow you to save/edit files as LF (like phpstorm). You can check the type of the file in the bottom right corner, in the status bar (you'll see LF or CRLF while a file is opened)
