How to install addons on the docker image

A few days ago I installed Home Assistant on my Synology NAS using docker and the homeassistant/home-assistant image as instructed on https://home-assistant.io/docs/installation/docker/ . I edited some settings in the config but now I would like to install some addons, like: https://home-assistant.io/components/sensor.pvoutput/. How would I install the pvoutput addon? I have searched the docs and the forum for few hours now but I didn’t find anything usefull. Thanks in advance!

It’s easy - nothing to install yourself, just add the following to your configuration.yaml, as per the docs:

sensor:
  - platform: pvoutput
    system_id: YOUR_SYSTEM_ID
    api_key: YOUR_API_KEY
    scan_interval: 120

Obviously add your system Id and API key in the appropriate places. Then restart Home Assistant. That’s it!

Wowww… that easy huh? Feel kind of stupid now. But thank you!
