Homematic integration no add integration button

Hi Community,

i am new to homeassistant and now in the process of setting up my first installation.
I was about to add homematic integration: Homematic - Home Assistant but don’t know how to do this as “Add integration” button is missing on the page of this integration. Also if i search the integration from my home assistant instance it is not appearing in the list.

Could you please advise how i can add homematic integration into my instance.

Thanks

This integration has no GUI.
You have to manually configure it in YAML, in configuration.yaml as explained in the doc.

thank you @koying - specifying details in configuration.yaml indeed helped
