+## Configuration options
+
+This feature should be enabled via a config option:
+```
+CONFIG_ZMK_MOUSE=y
+```
+This option enables several others.
+
+### Dedicated thread processing
+`CONFIG_ZMK_MOUSE_WORK_QUEUE_DEDICATED` is enabled by default and separates the processing of mouse signals into a dedicated thread, significantly improving performance.
+
+### Tick rate configuration
+`CONFIG_ZMK_MOUSE_TICK_DURATION` sets the tick rate for mouse polling. It is set to 8 ms. by default.

+## Acceleration
+
+Both mouse movement and scrolling have independently configurable acceleration profiles with three parameters: delay before movement, time to max speed and the acceleration exponent.
+The exponent is usually set to 0 for constant speed, 1 for uniform acceleration or 2 for uniform jerk.
+
+These profiles can be configured inside your keymap:
+
+```
+&mmv {
+    time-to-max-speed-ms = <500>;
