I might start with "An Application Binary Interface (ABI) is a way for programs to call other functions and use data structures from other compiled programs (binaries)" or something like that?

I wouldn't say "the library being required", because in the case of a native addon, it's actually the executable program that is being required.

I also wouldn't say "consuming" either, because that's too abstract. I can change it to "provider of the ABI" and "user of the ABI" to make it more down-to-Earth.

the Node.js project has adopted [semantic versioning](https://semver.org/). | ||
This ensures that the APIs provided by the project will result in a stable ABI | ||
for all minor and patch versions of Node.js released within one major version. | ||

N-API is versioned because new APIs are added from time to time. Unlike | ||
semantic versioning, N-API versioning is cumulative. That is, each version of | ||
N-API conveys the same meaning as a minor version in the semver system. |

I would link to the N-API and native-addon docs here perhaps?

You mean https://nodejs.org/docs/latest/api/addons.html and https://nodejs.org/docs/latest/api/n-api.html? I don't quite understand why I would link to the docs here?

I'm very +1 on adding this guide overall and it contains good content - left some nits -I think the start could be more new-user friendly in terms of motivating ABI.
