@hathach OK thach we now have 'nrf52840_usbboot' as a branch you can use here!
if you can fork this repo (instead of the microbuilder fork), we can take pull requests directly from you without bugging @microbuilder :)

i will also put you as a collaborator/reviewer so you can accept and review other pull requests if you want

also we will try to set up automation so on commits, binaries for bootloader and circuitpython will be built, that way you do not have to!

does that sound OK?

@ladyada ah thanks a lot, It makes lots of sense, I will fork and continue work there :D . For collaborator/reviewer, it is up to you. The CP repo is still quite comprehensive for me now ( haven't spent enough time to understand it fully), but I could help with the nrf52 PR if you like.

Yes only for nRF52 PRs of course :)
Sometimes @arturo182 has some suggestions or bugfixes so when he submits a fix or feature we would love to have you help look at it!
