Editing PeopleSoft Login Page

To make changes in the login page one has to change the signin.html page but all the text used by the .html is inside the text.properties
For miltilanguage instance it would be textXXX.properties
Example: To change the value of the login button from 'sign in' to 'developement' or something else one has to make changes in text.properties, signin.html & other few .html files refers text.properties for these values.
