@PttP You can check those pages at my local library to get a sense of what our project looks like. We're still getting going, just a couple months in. But it comes down to installing GNU/Linux (Mint) on donated computers as well as offering install assistance to folks that want to switch. Then, light support, classes at the library on using free software, GNU/Linux, Security/Privacy and more as we roll along. If you have a local library I'd suggest starting with them if you need a space.
