What should I do to use it

[Sooner or later]

Hi,

First if you use Arch Linux I planned to make an AUR package soon.
But for now, the only way is to clone the repo, install the required toolchain, and build it.

To install the toolchain follow the officials steps https://www.rust-lang.org/tools/install

Then in the repo run

cargo build --release

The binary will be available under /baru/target/release.

Of course you need the prerequisite installed in your system (see README.md)
