+doddns has two components. The first is a server, which runs on your DigitalOcean
 droplet (or any other remote server). It runs on port 18768 and responds to all
 HTTP requests with their source IP. The second is a client, which runs on your
 local computer. It fetches your IP address from the server and updates your
 DigitalOcean DNS for your chosen domain and subdomain with the address. Both the
-server and client save output to a log file (`doduc-server.log` and
-`doduc-client.log`, respectively).

 The server and client are designed to run continuously, so you will probably
 want to run them in the background. On POSIX operating systems, you can run
