Creating an instance
To create an instance, simply click on the Add Instance button on the top menu bar, or right-click an empty area in the middle of the launcher, and select Create instance.
Editing an instance
Once an instance is created, you can right-click it to open a context menu with some basic settings. From this list, select Edit Instance to access the edit menu.
Configure instance java
Prism Launcher does not yet automatically set the right version of Java for your instance. To manually select a version of Java, open the Settings window from the top menu bar, select the Java tab on the left sidebar, and under Java Runtime, click Auto-detect..., and then choose your version accordingly. Our Installing Java page has more information on the correct versions of Java for each Minecraft version.
