There are two ways of applying your MOTD to your Minecraft server, let´s see...
If you are just running a vanilla or Spigot based minecraft server, go to your server folder and search for a file named server.properties Among all the options you will find one named motd= ,just paste your MOTD there and done! It should look something like this: motd= \u00A7c\u00A7oYour incredible\u00A7r\n\u00A7dMinecraft server
If your server run through a proxy like bungeecord or velocity, go to your proxy folder and search for your config.yml Search for an option named motd:, and like in the vanilla/spigot section just paste your MOTD there. Restart your proxy and done! It should look something like this: motd: &c&oYour incredible\u00A7r\n&dMinecraft server
