Button-card fail to install

Hi everybody,
I failed to install the button-card integration published by @RomRider. Neither hacs worked (didn’t find any repository with this name) nor the manual installation (I copied the file “button-card.js” in my directory config/www but I do not find a file ui-lovelace-card.ymal) Do I have to create this file before?

Thanks in advance for your help!

A link to the integrations github page would be nice.

Here it is: https://github.com/custom-cards/button-card#manual-installation

Solved it! By installing manually!

  1. Copied “button-card.js” to config/www
  2. Added “/local/button-card.js” in ha - configuration - dashboards - resources (“resources” is accessed in the upper right corner of the Dashboards-window).
  3. Restart ha

The button-card then appears in the user interface (three dots - add card - see last entry)
