- On your local ARK, download the mods you want via Steam Workshop and take a not of the mod IDs (found in the URL of the Steam Workshop page)
- Open up ARK, click "HOST / LOCAL" (This will copy and extract the mods). You may need to wait a few minutes, and possibly even click "Host Non-dedicated Server" (and exit straight away).
- Close ARK, right click ARK in Steam, click Properties, click Local Files, click Browser Local Files and navigate to "\ShooterGame\Content\Mods".
- Select all the mods you want to include on your server (folders are named by the mod ids), including both the folder and the .mod files. Add to a .zip.
- Either via FTP or the control panel file manager, upload the .zip to your "/ShooterGame/Content/Mods" folder. You can then extract it via the file manager.
- In the control panel, go to Configuration Files and click Text Editor next the the settings.ini. Find the line "ActiveMods=" and add all the mod IDs seperated by a comma. (e.g. 141233,8321231,489341)
- Restart the server.
