You can customize your template by renaming buttons. This procedure is almost the same as Adding Author's name.

Take your text editor (preferably simplest like Notepad) and open your text.html file. Look at the picture below and find appropriate strings. They are button's titles. So first button's name is about me, second is exhibitions and so on. Just change button names.

DO NOT ADD OR DELETE ANY WHITE SPACES IN THE FILE! Edit only certain fragment of the text. Save file and upload it on your web server if you have edited your local copy of the text.html file. If you have edited remote copy of this file directly, just save it.
