+
+in your arduino sketch folder (often Documents/Arduino)
+add a folder called hardware (if it doesn’t exist
+then, inside hardware, create another folder with an arbitrary name (maybe fabBoards?)
+then, inside that folder, create another folder named avr
+then, inside avr, create a text file named boards.txt with the information below:
+    so, on my machine, all of that looks like:         
+        Users/Will/Documents/Arduino/hardware/fabBoards/avr/boards.txt
+
+hello.name=hello.arduino, ATmega328P, 5V, 8MHz internal oscillator
+hello.upload.protocol=arduino
+hello.upload.maximum_size=30720
+hello.upload.speed=57600
+hello.bootloader.low_fuses=0xE2
+hello.bootloader.high_fuses=0xDA
+hello.bootloader.extended_fuses=0x07
+hello.bootloader.path=arduino:atmega
+hello.bootloader.file=ATmegaBOOT_168_atmega328_pro_8MHz.hex
+hello.bootloader.unlock_bits=0x3F
+hello.bootloader.lock_bits=0x0F
+hello.build.mcu=atmega328p
+hello.build.f_cpu=8000000L
+hello.build.core=arduino:arduino
+hello.build.variant=arduino:standard
+
+with just these steps, the board should show up in your list of boards when you close and restart Arduino.
+
+in the new versions of Arduino, they’ve been organizing the boards in a new way with what they call “platforms”. If you want to make more similar boards and organize them under a subheading in the boards menu, you can create a platforms.txt file which names the heading and (optionally) provides additional compiler information.
+
+In this case, it can be as simple as:
+
+name=Fab Boards
+version=0.0.1
