How to bring links in cnc view YII2?

Question

Yii

Please tell me what instructions you need to write in web/urlManager/rules so that the links
- to the category were: /categoryname/
- the link to the article was: /categoryname/articlename , or even better just /articlename

And if you can explain how it is configured, according to the official documentation fails to do.

Now the links look like this:
https://sitename /site/category?slug=categoryname
https://sitename /site/post?slug=articlename

Tried:

// хлебные крошки
 'page/<page:\d+>'   => 'site/index',
'/'                 => 'site/index',

 // категория
 '<slug:>'           => 'site/category',

 // пост
  '<slug:>'           => 'site/post',

So either the CNC works on the category or on the record.
