Drupal 8 installation

The Pathauto module generates SEO-friendly titles for your content automatically.

It doesn't until you have configured it though.

The module itself doesn't provide any useful defaults or examples, as so often in all things Drupal.

So here you go for a quick start for content that uses taxonomy tags:

[node:field_tags:0]/[node:title]

if you don't use taxonomy, then just the title tag might be okay too.

Drupal is a bit of a Do-it-Yourself thing. Not just for any fancy "extras", but a lot of settings need to be manually set as well as modules or plugins installed that are needed to run a website. From my point of view at least.
