 ### Introduction
 We plan to make a gaming mouse using the shell of an old RZ01-0201 gaming mouse.
 
-### Intended features: 
-* movement
+### Features: 
+* cursor movement(obviously)
 * right and left mouseclick (mouse1/2)
 * sidebuttons (mouse4/5)
 * dpi buttons (2)
 * if time allows:
     * scrollwheel with button (mouse3)!!!!
 
-### Components we intend to use
+### Components:
 * Reuse of old side and dpi buttons (separate board with 5-pin cable to nucleo).
 * 2 D2F switches.
-* Scrollcomponent and scrollwheel button.
-* Custom nucleo board with MCU STM32F411RETx.
+* Custom nucleo board with MCU STM32F401RE
 * PixArt PMW3389 sensor
 * Shell of RZ01-0201
+* The rest of the components used is found in the Kicad project file, together with the PCB cutout and design.
 
 ### Software specs
-* Code language = Rust
-* Reliable communication
+* USB mouse driver written in Rust using RTIC
 *

 ### Pin connections
-All the connections can be seen in the kicad project files, for debugging, crystal, mouse buttons etc etc.
+All the connections can be seen in the kicad project files, for st-link, crystal, mouse buttons etc etc.
 
 The important connections are those that are going to be processed explicitly in the mouse driver code.
 ##### Buttons
 * PC6(36) = mouse2
 * PC7(37) = mouse1
-* PB12(33)
-* PB13(34)
-* PB14(35)
-* PB15(36)
-##### Sensor
+* PB12(33) = dpi2
+* PB13(34) = dpi1
+* PB14(35) = mb4
+* PB15(36) = mb5
+##### Sensor connected using SPI2 on 
 * PA15(50) = NCS
 * PC10(51) = SLCK
 * PC11(52) = MISO
