 - `minMagisk` tell the manager which is the minimum Magisk version required for the module
   (Often for magisk `xx.y` the version code is `xxyzz`, `zz` being non `00` on canary builds)
+- `needRamdisk` tell the manager the module need boot ramdisk to be installed
 - `support` support link to direct users when they need support for you modules
 - `donate` donate link to direct users to where they can financially support your project
 - `config` package name of the application that configure your module
   (Note: The icon won't appear in the module list if the module or target app is not installed)
+- `changeBoot` tell the manager the module may change the boot image
