The setting of the LEDs from left to right are:

LEDs	Description	Status
D7	Programming	when IC is programming properly
D8	Error	when target IC is not connecting properly
D9	Status: heartbeat	keep beating when power up

Support three attiny series
Some version of ArduinoIDE is not working well, for example, 1.61, 1.00, etc, better version approved 1.05, 1.56-r2
Burn bootloader twice, sometimes it seems the arduinoIDE bug: the IC will fail on uploading sketch when moved to arduino board

If you see the problem "programmer of out sync", get the easy solution here. arduinoISP
Find all the unofficial attiny board files here.

Series	DIP setup group	Auto-rest	ATtiny2313 jumper	Core file supported 1.5 IDE	LED
ATtiny13/25/45/85/2313/4313	1st group	up-off	Down-off and On-up for attiny*313	Link Source	D3
ATtiny24/44/84	2nd group	up-off	Down-off	Link
ATmega168/328	3rd group	up-off	Down-off	default in IDE	Digital pin 1 (D1)

upload arduino sketch using "programmer" options in the menu, DO NOT use "upload" button
Program hex file into target IC with AVRDUDESS

Set the auto-reset to off, now you will only program the target IC
Set the right jumpers for ICs, see the examples below, ONLY turn on one group of toggle switch every time.

For attiny13a, Turn on the 1st group on the left
For attiny 2313, turn on the 1st group in the left and put the four jumpers on the right top position
For atmega 328p, turn on the 3rd group on the right
For new board version attiny13
For new board version attiny2313
For new board version atmega328

Select the correct board and serial port
Select arduino as ISP in programmer menu (Your Arduino on the bottom should be already programmed within Arduino as ISP sketch, and heartheat LED is beating)
Click burn bootloader, do it twice for a bug reason (some arduinoIDE versions have problem)

To check the bootloader, you can try upload sketch
To upload sketch to the IC on the shield, choose "upload using programmer" in the menu, otherwise it will upload into arduino main board
or using avrdudess to upload AVR hex file
Do not program the LED pin 13, then LED on the shield will not work, use following settings instead

Series	Blink sketch for testing LED on shield
ATtiny13/25/45/85/2313/4313	int led = 4; (attiny13, etc), int led = 1;(attiny2313, etc)
ATtiny24/44/84	?
ATmega168/328	int led = 1;
