 For mod, modpacks, and world files that are not allowed for automated download, the container path `/downloads` can be attached and matching files will be retrieved from there. The subdirectories `mods`, `modpacks`, and `worlds` will also be checked accordingly. To change the source location of downloaded files, set `CF_DOWNLOADS_REPO` to an existing container path. To disable this feature, set `CF_DOWNLOADS_REPO` to an empty string.
 
-If the authors of the modpack have disallowed project distribution, then the desired **client** modpack zip will need to be manually downloaded and made available to the container. The path to that file must be passed to `CF_MODPACK_ZIP`. Similarly, the container path to a modpack manifest JSON can be passed to `CF_MODPACK_MANIFEST`. In either case, the modpack slug or page URL must still be provided.
+If you wish to use a unpublished modpack zip, set the container path to the file in `CF_MODPACK_ZIP`. Similarly, the container path to a modpack manifest JSON can be passed to `CF_MODPACK_MANIFEST`. In either case, **the modpack slug or page URL must still be provided**.
