+## Installing dfu-util
+
+The `dfu-util` suite of programs is used to talk to `Toboot`,
+the Tomu bootloader.  Most package managers have some form of
+`dfu-util` available.
+
+### Ubuntu and Debian
+
+````sh
+sudo apt-get install dfu-util
+````
+
+Create `/etc/udev/rules.d/10-tomu.rules` and populate it with the following:
+
+````udev
+ATTRS{idProduct}=="70b1", ATTRS{idVendor}=="1209", MODE="777"
+````
+
+(Note: you can give it a more restrictive mode if you also give it a group that you're in)
+
+### Fedora
+
+````sh
+sudo yum install dfu-util
+````
+
+### Arch
+
+````sh
+sudo pacman -Sy dfu-util
+````
+
+### Windows
+
+Download [dfu-util-static.exe](http://dfu-util.sourceforge.net/releases/dfu-util-0.8-binaries/win32-mingw32/dfu-util-static.exe) from the `dfu-util` repository and rename it to `dfu-util.exe`.  Place it somewhere in your $PATH for convenience.  To build examples, you'll also want to get [dfu-suffix.exe](http://dfu-util.sourceforge.net/releases/dfu-util-0.8-binaries/win32-mingw32/dfu-suffix.exe) and put it in your $PATH.
+
+### Mac
+
+Install [Homebrew](https://brew.sh/) and run:
+
+````sh
+brew install dfu-util
+````
+
 ## Compiling Samples
 
 To compile the samples, you will need an ARM compiler, `make`, and `dfu-util`.  The steps to install these files vary depending on your operating system:
