            This is a development release built from the **${{ github.ref_name }}** branch, at commit ${{ github.sha }}.
            The `${{ env.NIGHTLY_TAG }}` tag is moved to that commit on every build, so it always matches the binary attached below.

            It is **not** a stable release — for that, see [the latest release](https://github.com/soxoj/maigret/releases/latest).
            ${{ github.ref_name == 'dev' && 'The `dev` branch is more experimental than `main`. Unless you need a specific unreleased fix, prefer [the `main` development build](https://github.com/soxoj/maigret/releases/tag/nightly-main).' || '' }}

            ## How to run

            1. Download the attached `maigret_standalone.exe`.
            2. Either:
               - **Double-click it** — Maigret will ask you for a username, run a default search, and pause at the end so the output stays visible.
               - **Run it from a terminal** for full options. Press `Win+R`, type `cmd`, hit Enter (or open PowerShell), then:

                 ```cmd
                 cd %USERPROFILE%\Downloads
                 maigret_standalone.exe USERNAME
                 maigret_standalone.exe USERNAME --html       :: also save an HTML report
                 maigret_standalone.exe --help                :: list all options
                 ```
