+title: Create a server with a modpack
+description: Steps to import and customize startup settings for Modpacks
+keywords: [forge, create, server, create-forge-server, MCSS, mods, modded, modpack]
+---
+
+:::tip 
+This page should only serve as a guideline for what to do with modpacks.  
+Modpack creators often change how they create and manage server files, as such it is difficult to create guides for every possible type out there.  
+If you need additional help or if your server files look different from what we have in this guide, visit our [discord server](https://www.mcserversoft.com/discord).
+:::
+
+## Step 1: Determine if you need custom startup settings
+This is the first and most important step. We don't want to change settings if we don't need to.  
+Download the server files from your preferred website, and unpack it in a folder **that's not inside of the MCSS /servers/ folder**.  
+Then, check which case is yours:
+ - Server files don't contain any startup scripts (Good news! You can follow [the manual setup](/basic/create-server/Forge/create-forge-server-manually))
+ - Server files **ONLY** contain one or more .bat files (Go to [step 2](#-step-2))
+ - Server files contains PowerShell scripts (`.ps1`, `.psm1`, `.psd1`, ... )  (Go to [step 3](#-step-3))
+
+## Step 2: Modpacks with .bat startup files {#-step-2}
+This is the part where we may need to edit the contents of the startup .bat file.  
+Check the contents of your .bat file. Does it look like this? (If you have multiple of them, this section shouldn't apply to you)
+```batch
+REM Forge requires a configured set of both JVM and program arguments.
+REM Add custom JVM arguments to the user_jvm_args.txt
+REM Add custom program arguments {such as nogui} to this file in the next line before the %* or
+REM  pass them to this script directly
+java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.1-39.0.45/win_args.txt %*
+pause
+```
+Good news! You can now follow the [manual setup, from the "importing the server in MCSS" section](/basic/create-server/Forge/create-forge-server-manually#-migrate-the-server-to-mcss).  
+
+If your bat file(s) do not look like that, you can search the file for the real startup line, which should be something on the lines of
+```batch
+java %ARGS% -jar server.jar %MC_ARGS%
+```
+We need to find the `%ARGS%` and `%MC_ARGS` variables, once you do, copy them over in a new, different file, replacing where they should be in the startup line.  
+:::caution Run the default .bat file atleat once!
+We still suggest running the default .bat file atleast once, as in some cases it will install or download necessary mods or libraries.  
+It will also serve as an auto updater in most cases.  
+:::
+You can then import the server in MCSS, following [this guide](/basic/import-server/supported-server-files). **Make sure to select your newly created .bat file, and not the included one**.
+
+## Step 3: Modpacks with PowerShell scripts {#-step-3}
+Open the `start.ps1` file. If you don't have one, it means that your modpack likely isn't covered by this guide.  
+If you can see near the start of the file `Start script generated by ServerPackCreator`, you can go forward with this guide. If you don't see this, your modpack likely isn't covered by this guide.
+Open the `variables.txt` file, and copy the values of the `JAVA_ARGS` and `ADDITIONAL_ARGS`.
+Create a new `.bat` file, containing
+```batch
+java {JAVA_ARGS} -jar server.jar {ADDITIONAL_ARGS}
+```
+Replace the arguments with those you copied, without quotes and brackets.  
+:::caution Run the default .bat file atleast once!
+ServerPackCreator downloads and installs many requirements automatically. It is necessary to run it once.  
+We suggest disabling the "java check" in the variables.txt, to avoid installing JABBA, which is not needed if you use MCSS.
+:::
+After this you can import the server in MCSS, following [this guide](/basic/import-server/supported-server-files). **Make sure to select your newly created .bat file, and not the included one**.
