General write plugins and themes people will put it on github, in usrthe corresponding place can be a direct clone. You can also download the compressed package to the local and then spread on the server tar -xf.
cd usr/plugins/
git clone https://github.com/Dreamer-Paul/Pio.gitAlso note that the extract from the folder may be renamed, the name can not not work, then the next place of plug-ins will be emphasized, such as the above Live2d this plugin, you should name from the Pio-masterchange Pio.
Redeployment website into the background "plug-in management" or "Change Appearance", you can enable, configure a new plug-in theme.
Last reminder: Switch appearance will lead to the appearance of the original configuration (that is, "set the appearance" in the options) lost, if need back up.
