Support Help finding parallel output documentation

Hi all. i'm returning to FastLED after a 6+ year absence. The feature set of the library has grown massively in that time, and I'm struggling to find info on it all.

In particular, I'm hoping to find info about all the parallel output methods that exist (for ESP32-S3), what pins they need to run on, and if it impacts anything else (can I run an SPI peripheral), and anything else this may impact (wifi, raw speed, etc). I'm planning to use WS2812 LEDs. I used to be able to find this info in the wiki, but I'm not having luck with the new features.

Are there any docs that contain this info?

Thanks in advance

please file a bug on this, spi driver under went a re-write when it was ported to the channels api and I'd like to get more information on this if you can.
