Add a third-party released Volto Add-on in your project#
- Add the JS package as a dependency to your project: 
yarn add <name_of_addon>
- Update the - package.jsonto add the package name as a Volto addon:
"addons": [
    "@kitconcept/volto-blocks-grid"
],
If, instead, you want to add a Volto addon as a dependency to one of your development addons, you should run:
yarn workspace <myaddon> add <otheraddon>
And then you can edit the package.json of your development addon and add the
other Volto addon to the addons list (create it if it's not already there).
