Linux: unpack the archive and run ./install.sh. It puts Chimera in your home folder, adds a menu entry, and installs what it needs (Qt 6, OpenCV, libevdev, PipeWire, Java for the Minecraft agent) through your distribution's package manager, asking for your password once. Then run chimera from the menu or a terminal.

Windows: run the installer. It carries everything it needs and puts a shortcut in the Start menu. Cyclops and the launcher run on Windows; the Minecraft and Counter-Strike cheats are Linux only for now.

The app asks for your account first and opens the store once you are in.

Anything the web app put in your library is there when you sign in.
