 locate the modpacks for CurseForge at https://minecraft.curseforge.com/modpacks .
 
-There are a couple of options for obtaining an FTB/CurseForge modpack.
-One options is that you can pre-download the **server** modpack and copy the modpack to the `/data`
-directory (see "Attaching data directory to host filesystem”).

 Now you can add a `-e FTB_SERVER_MOD=name_of_modpack.zip` to your command-line.

-    docker run ... \
-      -e TYPE=FTB \
-      -e FTB_SERVER_MOD=https://www.feed-the-beast.com/projects/ftb-infinity-lite-1-10/files/2402889

-### Using the /data volume
-
-You must use a persistent `/data` mount for this type of server.
-
-To do this, you will need to attach the container's `/data` directory
-(see "Attaching data directory to host filesystem”).

-If the modpack is updated and you want to run the new version on your
-server, you stop and remove the container:
-
-    docker stop mc
-    docker rm mc
-
-Do not erase anything from your /data directory (unless you know of
-specific mods that have been removed from the modpack). Download the
-updated FTB server modpack and copy it to `/data`. Start a new container
-with `FTB_SERVER_MOD` specifying the updated modpack file.
