How do I inject certain files into certain websites from a chrome extension
<p>In my chrome extension I have multiple files that inject script into websites, I want to know how I can inject 1 file for a certain website. To better explain</p>

<p>My chrome extension has 1 file to inject into <a href="https://github.com" rel="nofollow noreferrer">Github</a> and another file to inject into a different website how would I inject each one into there own website <strong>without</strong> having both files injecting into each website. So each file will be injected into there own website.</p>
