Route groups are a powerful tool in the Laravel framework that allows you to group related routes together and apply common settings and attributes to all of the routes within the group.  

Step by Step:

1. Create your routes as you normally would in your routes/web.php file  

2. Wrap your related routes in a route group  

3. Give the group a prefix, middleware, and/or namespace if desired  

4. Add any other settings or attributes you need to apply to each of the routes  

5. Include the routes in the group  

6. Save and test the routes in your application
