Minecraft updates can bring new features, changes, and compatibility. Perfectly Optimized is designed to keep its configuration and included mods working together as the pack evolves. We try to update Perfectly Optimized as soon as possible whenever a new Minecraft version is released. However, some mods may take longer to update, which can delay a new release. If you don't want to wait, you can also check out the Beta or Alpha versions, as they may be available earlier. Keep in mind that these versions might have missing features, bugs, or compatibility issues.

This modpack runs on Fabric for Minecraft 1.21. The launcher you install it with sets that up for you.
Download the .mrpack file from Modrinth.
Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.
Give the instance enough memory: most modpacks want 4 to 8 GB.
To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
