 ## What this is
-DZGUI is a turnkey browser and mod manager for DayZ on Linux. It allows you to connect to both official and modded/community DayZ servers on Linux via a graphical user interface (GUI).
+DZGUI is a turnkey server browser and mod manager for DayZ on Linux. It allows you to connect to both official and modded/community DayZ servers on Linux via a graphical user interface (GUI).
 
 This overcomes certain limitations in the Linux client and helps prepare the game to launch by providing features like:
 
 - Search for and display global and LAN servers via an interactive table
 - Supports official, third-party, and modded DayZ servers
 - Automatically find and prepare mods being requested by servers
-- Add/delete/manage favorite servers by IP or ID
 - Quick-connect to favorite/recent servers
-- Manage local mods and symlinks
-- Prepare launch options to pass to Steam
+- Manage and delete local mods
+- And more
+
+## Design philosophy
+
+DZGUI follows a specific set of guidelines, enumerated below:
+
+- Provide a free and open-source tool under GPL
+- Do not use undocumented, third-party servers to aggregate data; no central "DZGUI" server
+- All connections go to Steam and DayZ servers directly; the tool should function in perpetuity without intermediary endpoints
+- Target Linux desktop and Steam deck specifically; not a cross-platform tool
