-Passport-C Media Player is a low-dependency SDL2 + FFmpeg prototype that recreates the 2004-era Passport DCT cable guide with live-seeking channels.
+FreePassport-C Media Player is a low-dependency SDL2 + FFmpeg application that is based on the look of interactive programming guide software used on older Cisco/Scientific Atlanta Explorer cable boxes, it allows you to organize your media into a virtual cable guide with live-seeking channels.

 For a fully portable setup, create a `media/` directory in the same folder as the AppImage and add your channel videos there. The AppImage will automatically detect and load channels from this directory.
