Hello, I bought a joomla template that used the K2. But I can not make some changes such as changing the button "read more", I wanted to customize the button, put in another text. Could anyone help me?
and also like to know how I can customize the template over sink.

Thanks

search for "READ MORE" in /root/languages/en-GB/en-GB.com_k2.ini and change the text there
Send a link and more info for your other question

Will the language file get overwritten during an upgrade, hence all changes lost?

Still learning ;)

Yes. Have a look here: Language String Overrides

You can override the K2 template as well. Look here:

• Templating with K2 (and the concepts of sub-templates)
• K2 template override package
