How to add LPC8N04 Development boards


I would like to work with the LPC8N04 and its corresponding evaluation board (LPC8N04 8 MHz | Arm® Cortex®-M0+|32-bit Microcontrollers (MCUs) | NXP Semiconductors) over platformio. I see that there are various LPC MCUs supported and I was wondering where to find info on how to add the LPC8N04 evaluation board to platformios portfolio. Can someone point me to some document, to get me started? Should I file an Issue on Github?

Apologies if this is the wrong way to go about this for board support, but did not want to spam Github right away.
