1. Download the most recent version of my map from:
https://minecraft.curseforge.com/projects/brann-presents-xiphias-a-ctm-adventure-map/files

Pay attention to the Minecraft version it's for.
Example: Xiphias 1.14pr2-19.04.15b || Xiphias {MINECRAFT_VERSION}-{DATE_UPDATED}

2. Download the Server Jar that matches the Minecraft Version of the map.
I recommend using https://mcversions.net/ This site has links to the Server Jar for many different Minecraft version. The files are all hosted on Mojang's servers, so they are safe to download and use.

3. Copy the map files into the "xiphias" folder located in this folder. That will look like this:

.\Xiphias Preconfigured Server DATE_UPDATED
	.\xiphias
		.\datapacks
		.\region
		.\icon.png
		.\level.dat
		.\resources.zip

4. Copy the "server.jar" file you downloaded into this folder.

5. Make sure each player adds "xiphias-resources.zip" from this folder into their Resources folder and turns it on in-game. (Default location for PC is "%appdata%\.minecraft\resourcepacks")

6. Run Launch.bat
(You can right-click on this file and select 'Edit' to see the command it is running.)

7. Have your friend connect to your IP. If they have trouble connecting you will want to Google "Port Forwarding Minecraft".
