Greetings!

I'm noticing that many contracts and jobs in the technical documentation field
require an understanding of programming code. This has always been a weakness
for me in my career since I haven't coded anything since the 80s (in basica of
all things).

If I wanted to learn how to write software code so that I'd be able to write SDK
or API documentation, or simply to be able to read code in order to write the
documentation, how would I start learning that?

I'm wondering what level of education I'd need to learn basic coding techniques
that would give me some insight in writing documentation about it. Is this about
get a BSc in programming, does it involve year-long course to get a certificate,
or is there something else?
