Anarchism depends on free exchange of information, I'll give a real life example from people without an anarchist ideology to make this more approachable:

I've recently installed an arch-linux based operating system, knowing that there is ArchWiki to depend on if i need guidance on specific issues, that is solely because the arch community tries to be helpful and documents almost every issue or thing one might need help with.

So now I, someone who's new to linux (albeit with existing knowledge in software overall) and arch specifically, does not need to know anyone personally to fix my own issues.

Do note about this example, that this approach is limited by my existing knowledge and also by how accessible the wiki is, BUT, in other, simpler situations I wouldn't be as limited in my scope.

TL;DR: as long as people can exchange information (ideas, recipes, etc) comfortably, we can expect they will, and we can depend on information sources (libraries, platforms, etc.) to hone our skills, fix whatever we need in the moment, or whatever else.

PS. All anarchists advocate for bringing about a reality in which we all have more free time, so that we may reap the fruits of this and many other aspects of life we want to improve, read about other ideas for a more in-depth explanation.

If you're interested in more, read about Tool Libraries, I'd go into more details about all this but this comment is getting long enough :^).
