I'm glad to hear that you're interested in helping with docs! We will be doing a lot of work on docs in the coming months and it will be great to have lots of people contributing. The maintainers are all busy with other tasks for the next few weeks. IPFS efforts are likely to roar back into full force activity in about 6 weeks (lots of well deserved vacations coming up), but the individual maintainers will each ramp up their engagement according to their availability over the next few weeks.
The main maintainers for the Go api client are @whyrusleeping and @kubuxu
