Right now it supports Linux, Mac OS, Windows, FreeBSD and DragonFlyBSD.

Here is an example what data you can fetch on these platforms (made with the assistant crate battery-cli):

Check out GitHub repo, documentation or my blog post with additional details.

Very cool, thanks also for that blog-post.

In the docs your link to the cli crate on crates.io is broken, btw
