Open up Notepad or another similar program and paste the seed into it. Keep it open for now as you will need it for the next step, but once that step is completed, it is a good idea to secure the seed. You could print a copy and then keep that hard copy in a safe place, or perhaps put the notepad file on a USB stick. Either way, you don’t want to keep your seed anywhere someone else can easily find it, so don’t keep it in a text file on your desktop or a centralized cloud server. You want to keep it safe but ‘off the grid’ if possible. So it would be a good idea to delete this notepad file after your seed is secured.
