 I tried to give credit whenever possible. If I have missed anyone, kindly add it to the list.

-On Linux (if you have installed through package), you shouldn't need to set anything other than your board type and port:
+You can either declare following variables in your project's makefile or set them as environmental variables.

+Keep in mind, that Arduino 1.5.x+ comes with it's own copy of avr tools which you can leverage in your build process here.

+Usefull Variables:
+
+The list of all variables that can be overridden is available at [arduino-mk-vars.md](arduino-mk-vars.md) file.
+
 - `BOARD_TAG` - Type of board, for a list see boards.txt or `make show_boards`
 - `MONITOR_PORT` - The port where your Arduino is plugged in, usually `/dev/ttyACM0` or `/dev/ttyUSB0` in Linux or Mac OS X and `com3`, `com4`, etc. in Windows.
 - `ARDUINO_DIR` - Path to Arduino installation. In Cygwin in Windows this path must be
   relative, not absolute (e.g. "../../arduino" and not "/c/cygwin/Arduino").
 - `ARDMK_DIR`   - Path where the `*.mk` are present. If you installed the package, then it is usually `/usr/share/arduino`
 - `AVR_TOOLS_DIR` - Path where the avr tools chain binaries are present. If you are going to use the binaries that came with Arduino installation, then you don't have to set it. Otherwise set it realtive and not absolute.
 
-The list of all variables that can be overridden is available at [arduino-mk-vars.md](arduino-mk-vars.md) file.
