The rusty-krab-manager is uploaded on crates.io (find it here). This is probably the best way to get it. To install, just run

cargo install rusty-krab-manager

You can now run the executable rusty-krab-manager at the terminal to launch.

@Orhun has been kind enough to make a AUR package. Download rusty-krab-manager with your preferred AUR helper.

Alternatively, you can use the git version. This might have features in development but is also more prone to breaking. In this case, run

git clone https://github.com/aryakaul/rusty-krab-manager
cd rusty-krab-manager
cargo run --release

Updating a cargo package is a little odd; however, I use and recommend cargo-update. With that package installed one can just run cargo install-update rusty-krab-manager to update to the latest version on cargo. If you're using the git version, just run git pull to get the latest git version of the repo.

NOTE: the rodio crate requires ALSA, if you encounter failed to run custom build command for 'alsa-sys v0.1.2' try installing libasound2-dev

NOTE: if either of the install methods above aren't possible, open an issue and let me know! I only use a Linux environment, but happy to try and make the install process for others!
