NodeBB admin dashboard offers a UI to install plugins and themes in their dashboard. However, some plugins/themes may need to be installed by hand. To do so, use the Web terminal:
cd /app/code /usr/local/bin/gosu cloudron:cloudron npm install nodebb-theme-timuu
After installation, restart the app and activate the plugin in the NodeBB dashboard.
The list of plugins can be viewed as follows:
cd /app/code ./nodebb list
Plugins can sometimes make NodeBB not start up. To fix this, first pause the app and then
cd /app/code ./nodebb reset -p nodebb-plugin-pluginname
