This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

MITHOS is a modular, system-agnostic digital toolkit designed to stay out of your way so you can focus on what's important: Telling stories with your friends.

Built by a DM for DMs, MITHOS replaces the cluttered experience of running games through multiple browser tabs and cloud-dependent subscriptions with a light-weight, locally-stored dashboard.

Total Creative Freedom

Unlike platforms that lock you into specific rulesets, MITHOS is built to be system-agnostic. Whether you’re running high-fantasy, sci-fi, or a gritty homebrew survival horror, the toolkit adapts to your workflow; not the other way around.

"Infinite" Canvas

Stop digging through nested menus. MITHOS utilizes a free-panning, scrollable workspace that mimics a physical table. Spread out your NPC portraits, maps, and trackers exactly where you need them and see your entire session at a glance.

Key Features:

• No Subscriptions: Buy it once, own it forever. Privacy is a right, and your data stays on your machine.

• 100% Offline Reliability: No internet required. Your tools are always accessible, ensuring your game is never interrupted by outages or paywalls.

• Zero-Tab Integration: View and update your notes from Obsidian, OneNote, or Notion directly within the dashboard. Stop "Alt-Tabbing" and keep the immersion alive.

• Player-Facing Screens: Manage the behind-the-screen stuff on your device while projecting a clean map or combat tracker for players on a second display or digital TV table.

• Modular Tools: Includes a Party Tracker, Combat Tracker, NPC Generator, NPC Library, Bestiary, Session Viewer (OneNote and Obsidian compatible), Shop Generator, Weather Tool, Custom Calendar, Timekeeper, Map Display, Session Recorder, Sticky Notes, Dice Roller, Custom Layouts, Multiple Campaign Support, and more...
