+# BongoCat
+
+BongoCat is a desktop companion for macOS and Windows. A Live2D cat lives on your screen: its eyes and
+paws follow your mouse, and it plays a motion for every key, mouse button and gamepad button you press.
+It sits quietly in a corner until you want it again. BongoCat is written in Rust, the settings window is
+built with gpui-kit, and the cat itself is drawn by a native Metal or D3D11 renderer that is completely
+separate from the settings UI.
+

+
+## The cat on your desktop
+
+The model window is a frameless overlay that you can drag anywhere, resize, scale, make more or less
+transparent and round the corners of. It can stay above other windows, let mouse clicks pass straight
+through it, stay inside the screen edge, or hide when the pointer comes near and come back after a delay
+you choose. A frame rate cap keeps it quiet on a laptop battery.
+
+## A cat that answers every press
+
+Keyboard, mouse buttons and gamepad buttons are three independent inputs, and each one can be muted on
+its own from a global shortcut, so the game you are playing never makes the cat twitch. Mouse tracking can
+be flipped horizontally or vertically when the cat should follow the pointer the other way. Gamepad sticks
+and triggers have their own dead zones, and the model can switch by itself when a controller connects or
+disconnects, or stay pinned to the model you picked.
+
+## Make the model behave the way you like
+
+Mirror the model horizontally, play motion sounds, and let the cat play random motions or expressions on
+an interval you set instead of sitting still. Each model remembers the expression you last used on it, so
+switching back to a favourite cat brings back the look you left it in.
+
+## Bring your own model
+
+BongoCat ships with a small set of built-in models, and the model library imports your own Live2D models
+from a folder you choose or drag onto the window, with the cover image captured for you. Models can be
+renamed and given a new cover, and apps made with Bongo-Cat-Mver are converted on import. A model that
+fails to load never takes the current one down: the cat you already have stays on screen while the new one
+is validated.
+
+## Shortcuts and housekeeping
+
+Global shortcuts open the settings window, mute an input source and trigger model behavior, and the two
+shortcut groups have independent switches, so window shortcuts can stay on while model shortcuts are off.
+BongoCat can open at login, keep a menu bar or taskbar icon, check for updates on an interval, and keep
+logs only for as long as you want, at the level you want. An automatic update checks the version, the
+platform and the signature before anything is replaced, and a failed update rolls back.
+
+## Open and offline
+
+BongoCat is open source under the Apache License 2.0. It never touches the network while you use it,
+collects nothing, and every model, setting and log stays in a plain file in your own user directory.
