Share your Google Add-ons with other Google Docs users
Now that your first Google add-on is ready, you may want to distribute it to other users of Google Docs. The easiest option would be that you share your document with public and set the permission as Anyone can view. Now anyone can create a copy of your document in their own Google Drive and use your add-on.
Google Add-ons can also be published to the Chrome store, the process is similar to publishing Chrome extensions, but this isn’t available to all Google developers yet.
