 ## Documentation
 This template is using [Nebular](https://github.com/akveo/nebular) modules set, [here you can find documentation and other useful articles](https://akveo.github.io/nebular/docs/guides/install-based-on-starter-kit).
 
-### ng2-admin
-We will continue supporting [ng2-admin](https://github.com/akveo/ngx-admin/tree/ng2-admin) version, but if you are starting from scratch we recommend using `ngx-admin`. Unfortunately, there is no way to automatically update from ng2-admin to ngx-admin, but some parts (Nebular components) could be manually included.
