+Notice: we can do this on the staff end easier then clients can.
+
+To change server cores, follow these steps:
+
+1. **Download the jar or files for the server:** Locate and download the desired server core or files that you want to use.
+
+2. **Upload the files to the server:** Access your server files and upload the downloaded jar or files to the root of the server.
+
+3. **Modify the startup command:** Find the startup area for your server. Under  `SERVER JAR FILE`, Replace the current jar file name with the new file's name.
+
+   Example: if the new jar file is named `arclight-forge-1.16.5-1.0.24.jar`, modify the startup command to `arclight-forge-1.16.5-1.0.24.jar`.
+- Forge: run the forge server installer locally, which will make the  forge-jar and the libraries folder.
+   - To use newer forges, after the files are moved to the server, you can set the server jar file to some similar to the following: @libraries/net/minecraftforge/forge/1.19.4-45.0.49/unix_args.txt, as it will be different depending on what version you are on.

+
+4. **Restart the server:** The server will now use the new jar file as the server core.
