 # extension
 
 movie-web extension, allows providers to work without proxy
+
+## How this will likely work on the app
+
+**On mp4 streaming:**
+1. movie-web application will send the following to the extension:
+   - full specific URL for streaming URL
+   - preferred headers for the streaming URL
+2. extension will set rules for the specific URL:
+   - CORS headers, allow cross origin
+   - Set preferred headers sent by app
+
+**On HLS streaming:**
+1. movie-web application will send the following to the extension:
+   - hostname for the streaming CDN
+   - preferred headers for the streaming CDN
+2. extension will set rules for the CDN hostname:
+   - CORS headers, allow cross origin
+   - Set preferred headers sent by app
+
+**On scraping request:**
+1. movie-web application will send the following to the extension:
+   - url it will attempt to scrape
+   - list of headers it's planning on reading
+   - list of headers it should add
+2. extension will set rules for the list of URLS:
+   - CORS headers, allow cross origin
+   - set readable headers in CORS
+   - set the headers for sending the request
+3. extension will reply with the rule ID
+4. movie-web will execute the request
+5. movie-web will tell the extension to remove the rule with the rule ID
+
+## How will this work for other domains?
+- The popup will allow adding/removing the current tab domain to allowed domains list
+- The extension will not listen to any calls from disallowed domains
+- movie-web.app is default in the list of allowed domains
