Broken link: Build a Google+ clone with Django and AngularJS (Angular 1.x)

The tutorial link in the Angular section is broken and returns a 502 Bad Gateway error.
Tutorial Name: Build a Google+ clone with Django and AngularJS (Angular 1.x)
Broken Link: https://thinkster.io/django-angularjs-tutorial
Location in README: Angular section

Expected Behavior

The link should direct users to a working tutorial or be removed from the list.

Current Behavior

When clicking on the tutorial link, the browser shows:

• 502 Bad Gateway ERROR
• Message: "The request could not be satisfied"
• The website appears to be permanently down

Possible Solution

Remove the broken link or replace it with a similar working tutorial.

Steps to Reproduce

1. Go to the README.md file
2. Navigate to JavaScript > Angular section
3. Click on "Build a Google+ clone with Django and AngularJS (Angular 1.x)" link
4. Observe the 502 error

El enlace roto aparece en README.md bajo JavaScript > Angular. Empieza comprobando el tutorial enlazado y las entradas circundantes; después, elimina el enlace muerto o sustitúyelo por un equivalente funcional. La tarea está terminada cuando README ya no dirige a los lectores a la página 502 y el enlace actualizado, si se utiliza, se abre correctamente.
