Want to know how to brand or whitelabel a plugin

Hello here are some words on the wpmudev site i wish to understand:slight_frown: t’s easy to translate any WPMU DEV plugin or theme, and it’s equally easy to white-label them so your clients or users never know your secret source. As 100% GPL code, you’re even free to edit our plugins and themes as much as you like, no questions asked.)

so my questions is how to whitelabel a plugin?
