          ## Installation

          You have multiple options to install i3nator:

          1. Download the static binary from this release. This will work without any additional dependencies.

          2. If you have at least Rust 1.56.1 with Cargo installed, you can install i3nator directly from crates.io:

              ```console
              $ cargo install i3nator
              ```

              If you are updating i3nator through cargo, just use:

              ```console
              $ cargo install --force i3nator
              ```

              In case you want to install this specific version, you can specify the `--version` argument:

              ```console
              $ cargo install --force --version ${{ steps.tag.outputs.value }} i3nator
              ```

          3. Another option is to install from directly from source (this requires at least Rust 1.56.1):

              ```console
              $ git clone https://github.com/pitkley/i3nator.git
              $ cd i3nator
              $ cargo install
              ```

          **Note:** If you want to be able to use the automatic command execution feature, you will need to install [`xdotool`][xdotool].
