To upload mods to your server, you will have 2 options, to either add the mod to a newly generated world, or to add the mod to an esisting world. First, I will explain how to add the mods to a world that has not yet been geneareted. After, I will explain how to add mods to a preexisting world.

To add mods to a new world is much simpler than adding mods to a preexisting world, simply follow the steps below.

*Note: This will need to be done when there is no world with the name of the world in the configuration editor.*
1. Open up your configuration editor.
2. Find the section that says mods.
3. Type <unsignedLong>00000000000000000</unsignedLong> but replace 000000000000000 with your mod ID, which can be found as the last part of the mod URL.
4. Simply click save and start the server.

To add mods to a preexisting world, you will need to do the previous to add all the mods to the mods section in the configuration files.

*Note: Only do this once you have added all the mod IDs you want to the configuration files*
1. Open up the file manager.
2. Open the saves folder.
3. Find the folder with the name of the world you want to add the mods to, open it.
4. Once inside the file, located the sandbox.sbc file.
5. Click edit the sandbox.sbc file.
6. In the sandbox.sbc file, locate the location that says <Mods/>
7. Replace <Mods/> with
 <Mods>
    <ModItem>
      <Name>Mod ID.sbm</Name>
      <PublishedFileId>Mod ID</PublishedFileId>
    </ModItem>
    <ModItem>
  </Mods>

8. In the location that says Mod ID, replace it with your mods ID
9. If you want to add multiple mods, you will need to add more
    <ModItem>
      <Name>Mod ID.sbm</Name>
      <PublishedFileId>Mod ID</PublishedFileId>
    </ModItem>
to the sandbox.sbc, the following will be an example of adding 3 mods.

Example:

  <Mods>
    <ModItem>
      <Name>Mod ID.sbm</Name>
      <PublishedFileId>Mod ID</PublishedFileId>
    </ModItem>
    <ModItem>
      <Name>Mod ID.sbm</Name>
      <PublishedFileId>Mod ID</PublishedFileId>
    </ModItem>
    <ModItem>
    <ModItem>
      <Name>Mod ID.sbm</Name>
      <PublishedFileId>Mod ID</PublishedFileId>
    </ModItem>
    <ModItem>
  </Mods>
