The DeckyVault plugin is now available for Steam Deck! Record performance metrics directly from the Quick Access Menu and upload them to DeckyVault.

How it works:

1. Add ~/deckyvault-mangohud.sh %command% to your game's Steam launch options
2. Launch the game and get to gameplay
3. Open the Quick Access Menu and press Start Recording
4. Play for a bit, then press Stop Recording
5. Export to a .deckyvault.json file or upload directly to DeckyVault
