 1. **Run the source code directly:**

 2. **Run prebuilt executables:** <br>
    Alternatively, you can download and run prebuilt binaries of xaif from the CI. They are available from
    the [releases page](https://github.com/m0nac0/xaif/releases) (as Assets) or
    from [any successful CI Workflow run](https://github.com/m0nac0/xaif/actions/workflows/main.yml?query=branch%3Amain)
