+This is a simple Laravel app for a blog website to demonstrate key features of this web framework
 
-Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable, creative experience to be truly fulfilling. Laravel attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as authentication, routing, sessions, and caching.
+Companion slides: https://www.dropbox.com/s/nmi8sryhnl8voqo/eouyang_cs50_laravel-seminar_slides.pdf?dl=0
 
-Laravel aims to make the development process a pleasing one for the developer without sacrificing application functionality. Happy developers make the best code. To this end, we've attempted to combine the very best of what we have seen in other web frameworks, including frameworks implemented in other languages, such as Ruby on Rails, ASP.NET MVC, and Sinatra.
+It is recommended that you run this example on the CS50 Appliance
 
-Laravel is accessible, yet powerful, providing powerful tools needed for large, robust applications. A superb inversion of control container, expressive migration system, and tightly integrated unit testing support give you the tools you need to build any application with which you are tasked.
+### Setup
 
-## Official Documentation
+1. Install composer (for dependency management)
 
-Documentation for the entire framework can be found on the [Laravel website](http://laravel.com/docs).
+`curl -sS https://getcomposer.org/installer | php`
 
-### Contributing To Laravel
+`sudo mv composer.phar /usr/local/bin/composer`
 
-**All issues and pull requests should be filed on the [laravel/framework](http://github.com/laravel/framework) repository.**
+2. Download the repository.
 
-### License
+Distribution code: `git clone https://github.com/ericouyang/blog50.git`
 
-The Laravel framework is open-sourced software licensed under the [MIT license](http://opensource.org/licenses/MIT)
+Completed example: `git clone -b completed https://github.com/ericouyang/blog50.git`
+
+3. Navigate into the new `blog50` folder and install dependencies
+
+`composer install`
+
+4. If you're running the completed example, you need to create the database called `blog50` and then run
+
+`php artisan migrate`
+
+5. Run the server using
+
+`php artisan serve`
+
+6. Go to this in your browser
+
+`http://localhost:8000`
