How to use the Platinum Mod guides
The eight guides are designed as task-based references rather than a single article that must be read from top to bottom. Start with the problem you have now. If you are still choosing a source, read the Download and Versions guides. If you already know which repository you intend to use, move to Installation and Compatibility. Troubleshooting, Progression and Backup Safety become most useful once you have a real test profile and can compare expected behavior with what you see in game.
Keep your own setup record
As you follow a guide, write down the repository, revision or archive you used, plus the game version, loader, Java runtime and dependencies. These notes turn a one-time successful installation into something you can reproduce later. They also make troubleshooting faster because you can compare a failing profile with a known-good configuration instead of reconstructing the environment from memory.
Use clean tests before modpack tests
When a guide asks you to verify startup, recipes, content or saving behavior, begin with the smallest possible profile. A clean profile gives you a baseline. After that baseline works, add other mods in small groups. If a problem appears, the last small group is a much narrower search area than a full modpack with dozens of simultaneous variables.
Protect important worlds
Guide steps that involve a new build, dependency change or loader change should be tested on a disposable world or a copy first. Keep backups outside the active game directory and confirm that you can restore them. The Backup and Safety guide covers a more complete rollback workflow for ongoing use.
