- [Sync modes](https://xichil.dev/wiki/settings-saver/v0/mechanics/sync-modes/index.md): What Settings Saver does at launch and while you play in each sync mode (Off, Auto, Auto + always apply), and what the one-time apply is.
- [Converting between versions](https://xichil.dev/wiki/settings-saver/v0/mechanics/version-conversion/index.md): How Settings Saver keeps one copy of your settings that works on every Minecraft version from 1.7.10 to 26.3, and which settings change along the way.
- [Running several instances at once](https://xichil.dev/wiki/settings-saver/v0/mechanics/multiple-instances/index.md): How Settings Saver keeps its store consistent when several Minecraft instances run at the same time, and whose change wins when two of them sync.
