When preparing my voice assistant, there are apps regarding to the command “sam install skills”.
I don’t know where to execute this command…
I’ve already logged into the snips docker container via portainer as root, but could not found the command.
Or is this step not needed making an app work properly? 
You should download the assistant manually and then upload it to the share folder exposed by the samba plugin
The filename should be the same as the one you configured in the Snips Addon, defaulted to “assistant.zip”
Thanks for your reply. The manual procedure is no problem, have done it already.
I would like to know: Does the manual way lacks some features as some apps suggest to use this sam command… 
Well, the manual is written for Snips running on a Pi, not running Snips as an Addon for HassIO
