+Do not edit `/etc/resolv.conf`. It will likely be replaced by NetworkManager.
+<!--more-->
+Open a shell and add nameserver for existing connection.
+
+```bash
+nmcli con $ssid ipv4.dns "1.1.1.1 1.0.0.1"
+```
+The SSID can be found with `nmcli con`.
+
+Replace the IP addresses to your desired ones.
+
+Now restart the connection to apply the changes.
+
+```bash
+nmcli con down $ssid
+nmcli con up $ssid 
+```
+
+Verify with `cat /etc/resolv.conf`.
