+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`.
 
 The latest file will be located and used by default, but if a specific version is desired you can use one of the following options. With any of these options **do not select a server file** -- they lack the required manifest and defeat the ability to consistently automate startup.
