A couple of announcements.

Firstly, we're delighted to host a presentation by @[email protected] of @[email protected] on Wednesday January 15th. Sign up to attend here: https://www.meetup.com/London-Bitcoin-Devs/events/267663259/

@michaelfolkson @jon @harding thanks for writing on this !

just noting: although most of the good first issues require Python or C++, there's also some "good first issues" that require only shell scripting knowledge; see for example https://github.com/bitcoin/bitcoin/issues/17506
