+## How it works
+
+Honestly its probably more complicated than needs to be but i based it off of other extensions that do the same thing.
+
+- inject `content-script` into every page
+- script pings `background.js` that there is a new page
+- `background.js` activates the "browser action" (the little logo on the browser bar) if its a Netlify site by sniffing the `Server` field in the response header.
+- if it is a Netlify site and you click the "browser action":
+  - if it is on `.netlify.com` host, `popup.js` checks if it is open source and manipulates `popup.html` accordingly.
