Usage
Installs the Trestle gem and optionally adds trestle-auth and trestle-search.

If you wish to use Devise with trestle-auth, ensure that you have installed and configured Devise first and created a user model.
If not using Devise, the template will create a login [email protected] / admin.

Run this command in your Rails app directory in the terminal:

rails app:template LOCATION="https://railsbytes.com/script/zmnsyx"
