JTAG Debugging

I want to debug the chip via JTAG, so I ordered the SEGGER J-Link, and am now wondering how to connect it. I have the Adafruit Huzzah board and not much exprience. Did anyone try this? Which pins go where? Do I need pulll-downs? Does the ESP8266 support SWD or only full JTAG?
There is surprisingly little information available.

Hi, I had the same question half a year ago, then I discovered VisualGDB. They support both jtag and serial debug interface (unfortunately not SWD as the chip doesnt support this).
They provide a lot of tutorials. It is based on VisualStudio IDE.

There are no information simply because there is no SWD or JTAG port on the hardware.

Not true, there is jtag support and as alternative for swd, the gdbstub serial interface...
I have experience with both.
