KM-HUD is a QBCore resource in the Angelinn142/km-hud repository. Its manifest requires qb-core and loads html/ui.html; the client code displays cash, bank balance, job and job grade. The HUD toggle command is /zshud.
Copy the inner km-hud folder containing fxmanifest.lua into your test server resources directory. Start qb-core before km-hud. Check the display after joining, changing jobs and updating money; also test reconnecting and restarting the resource. These checks are necessary because reviewing the source does not establish compatibility with your server configuration.
