+## How it works?
+
+Domains feature gives you option to easily map your domain to your Prem App application.
+It is necessary to insert two A records:
+- A `example.com` to `<IP_GATEWAY>`
+- A `*.example.com` `<IP_GATEWAY>`
+You can also use a subdomain ie. `prem.example.com` and `*.prem.example.com`
+
+After this is done you need to add your domain in **Prem App > Settings > Domains**, and you are ready to go.
