Remove service worker

README.md

 Large files such as NW.js, Electron, and WKWebView executables are stored on an external server outside of this repository. While we aren't actively removing old files (the server still serves files unused since November 2020), we can't promise they will exist forever. The packager uses a secure checksum to validate these downloads. Forks are free to use our servers, but it's easy to setup your own if you'd prefer (it's just a static file server; see `src/packager/large-assets.js` for more information).
 
-### Service worker
-
-Set the environment variable `ENABLE_SERVICE_WORKER` to `1` to enable service worker for offline support (experimental, not 100% reliable). This is not recommended in development. Our GitHub Actions deploy script uses this by default.

 ## Standalone builds
 
 The packager supports generating "standalone builds" that are single HTML files containing the entire packager. Large files such as Electron binaries will still be downloaded from a remote server as needed. You can download prebuilt standalone builds from [our GitHub releases](https://github.com/TurboWarp/packager/releases). These can be useful if our website is blocked or you don't have a reliable internet connection. Note that standalone builds do not contain an update checker, so do check on your own occasionally.
