How do I install a Minecraft modpack (CurseForge or Modrinth)?
Modpacks come in two flavours: server packs (pre-configured, ready to run) and client packs (needs conversion). Always download the server pack if one is available; it includes the correct Forge or Fabric version and all the required mods already configured.
For a CurseForge server pack: download the server pack ZIP from the modpack's CurseForge page. Extract it and upload all the contents to your server root via File Manager. The pack includes a forge-<version>-installer.jar or similar; check the included README or start.sh to find the correct JAR filename, then update your server's start command on the Startup page to use that JAR. Most server packs also include a server.properties and eula.txt; accept the EULA in that file before starting.
For a Modrinth pack: download the .mrpack file and use the mrpack-install tool (available from GitHub) to extract a server-ready directory, then upload the contents.
RAM requirements: modpacks need significantly more RAM than vanilla. A medium modpack (100-200 mods) typically needs 4-6 GB. A large pack (300+ mods) may need 8 GB or more. Check the modpack's recommended server RAM on its CurseForge or Modrinth page and ensure your plan meets it.
After uploading, start the server and watch the Console page. The first start is slow as Forge or Fabric loads all mods. Errors on first start are common; read the Console output carefully. "Missing dependency" errors mean a required mod was not included; download and upload it manually. "Incompatible mod set" errors mean two mods conflict; check the modpack's known issues page.
