Question About Modifying The HTML5 Blank Theme. HELP!

I had downloaded the HTML5 Blank WordPress Theme, I noticed a lot of functions within the function.php that use ’ html5blank '.

Example: // Localisation Support

load_theme_textdomain('html5blank', get_template_directory() . '/languages');

What I want to know is, can I just go ahead and replace the ’ html5blank ’ with my domain name?

Example: // Localisation Support

load_theme_textdomain('mysite', get_template_directory() . '/languages');

Is it normal for people to ’ Tweak, Modify or Change ’ this and the functions to switch from ’ html5blank ’ to ones domain name?

Thank you

That’s just a “hook” for language support. You can change the name to anything you want. If you wanted to translate your theme (not your site’s content, but the theme itself) into various languages, then you’d use that hook. If you don’t intend to use it, you don’t need it.
