+## TODO / Special Features
+- [x] Track upstream (AltServer-Windows) develop branch (i.e. Beta version)
+- [x] Support Offline Anisette Data Generation (i.e. without Sideloadly)
+  - Finsihed, please run [alt_anisette_server](https://hub.docker.com/r/nyamisty/alt_anisette_server) & use `ALTSERVER_ANISETTE_SERVER` to specify custom server URL
+- [x] Support Wi-Fi Refresh
+  - [netmuxd](https://github.com/jkcoxson/netmuxd) now supports network devices, but needs a special env var `ALTSERVER_NO_SUBSCRIBE` to allow it work correctly. Enabling this would disable **auto-refresh when plugged-in** of USB devices
