Whether you are completely new or are a seasoned professional this article is the complete guide to getting your server completely up and running. If you are new all of this may seem very confusing so in this article, we will hopefully clear up the confusion.

Getting Started

Before we get started you will need a server. You can view all of our Minecraft hosting plans here. Once you have purchased a server, you will receive an email on how to set up your control panel account. Once you set up your control panel account you can access the control panel here. Now that you are here we are ready to get started.

1. Select your server version. We have a very extensive list of server versions to choose from under the Versions tab. Note, Minecraft version 18 requires Java 17 to run. More on changing java versions later.

2. Now that you have selected a version, head over to your file manager

3. Locate eula.txt and open it. We recommend that you read and understand Mojang's Eula, it can be found here

Getting started - steps

4. Once inside eula.txt, you will see eula=false. You need to change this to eula=true then save the file and return to your console.

5. Now your server is all set up!

Changing Java Version

Based on the Minecraft version selected you will need to change your java version.

1. Navigate to the startup tab

2. Click the dropdown under docker image

3. Select your desired java version
