    <summary><h2>Installation and signature verification</h2></summary>

    ### Installation
    
    #### By downloading binary from the release

    For instance, if you are using Linux on an AMD64 architecture:
    ```shell
    # Download the binary
    curl -LO https://github.com/{{ .Env.GITHUB_REPOSITORY }}/releases/download/{{ .Tag }}/{{ .ProjectName }}-linux-amd64

    # Move the binary in to your PATH
    mv kapp-linux-amd64 /usr/local/bin/ytt

    # Make the binary executable
    chmod +x /usr/local/bin/ytt
    ```

    #### Via Homebrew (macOS or Linux)
    ```shell
    $ brew tap carvel-dev/carvel
    $ brew install ytt
    $ ytt version  
    ```

    ### Verify checksums file signature

    The checksums file provided within the artifacts attached to this release is signed using [Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub OIDC(Refer [this](https://docs.sigstore.dev/system_config/installation/) page for cosign installation). To validate the signature of this file, run the following commands:

    ```shell
    # Download the checksums file, certificate and signature
    curl -LO https://github.com/{{ .Env.GITHUB_REPOSITORY }}/releases/download/{{ .Tag }}/checksums.txt
    curl -LO https://github.com/{{ .Env.GITHUB_REPOSITORY }}/releases/download/{{ .Tag }}/checksums.txt.pem
    curl -LO https://github.com/{{ .Env.GITHUB_REPOSITORY }}/releases/download/{{ .Tag }}/checksums.txt.sig

    # Verify the checksums file
    cosign verify-blob checksums.txt \
      --certificate checksums.txt.pem \
      --signature checksums.txt.sig \
      --certificate-identity-regexp=https://github.com/{{ .Env.GITHUB_REPOSITORY_OWNER }} \
      --certificate-oidc-issuer=https://token.actions.githubusercontent.com
    ```

    ### Verify binary integrity

    To verify the integrity of the downloaded binary, you can utilize the checksums file after having validated its signature.
    ```shell
    # Verify the binary using the checksums file
    sha256sum -c checksums.txt --ignore-missing
    ```
