Former CCNA+S needs help with new IOS-XE (Cisco ISR 1111-9P-LTE)

Hi !

I used to be certified CCNA+S back in 2010. I was running the company I work for since then with gear that I was able to configure and troubleshoot but now I have introduced a new device running IOS-XE and I need to get back to the basics.

Can someone post a configuration template for a branch office directly connected to the internet.

The official configuration guide (cisco_1100_series_swcfg_xe_16_7_x.pdf) isn't helping a lot for now.

Thank you.
