 Download and Install
 --------------------
 ### 1. Install Tools
-First, you need tools to build firmware and program your controller. I assume you are on Windows here.
 
-1. **Toolchain** Install [WinAVR][winavr]. This is old but works well for this purpose. `WinAVR` is a tool set to build firmware including C compiler(gcc) and make commands. You can use [CrossPack][crosspack] instead if you are on Mac.
+1. **Toolchain** On Windows install [MHV AVR Tools][mhv] for AVR GCC compiler and [Cygwin][cygwin](or [MinGW][mingw]) for shell terminal. On Mac you can use [CrossPack][crosspack]. On Linux you can install AVR GCC with your favorite package manager.
 
-2. **Programmer** Install [Atmel FLIP][flip]. `FLIP` is a tool to program(load) firmware into AVR controller via DFU bootloader. AVR USB chips including ATmega32U4 has DFU bootloader by factory default. You can also use [dfu-programmer][dfu-prog] instead if you are on Mac or Linux.
+2. **Programmer** On Windows install [Atmel FLIP][flip]. On Mac and Linux install [dfu-programmer][dfu-prog].
 
-3. **Driver** At first time you start DFU bootloader on Chip 'Found New Hardware Wizard' will come up on Windows. If you install device driver properly you can find chip name like 'ATmega32U4' under 'LibUSB-Win32 Devices' tree on 'Device Manager'. If not you shall need to update its driver on 'Device Manager'. You will find the driver in `FLIP` install directory like: C:\Program Files (x86)\Atmel\Flip 3.4.5\usb\. If you use `dfu-programmer` install its driver.

 If you use PJRC Teensy you don't need step 2 and 3 above, just get [Teensy loader][teensy-loader].
