"How to keep 1Password up to date" page lacks Linux instructions

Hi there! Thanks for bringing this up. I have passed this on to our documentation team for review, so we can make sure everything is up to date and that folks are able to use it to get the information they need.

For future reference, if you're in the 1Password for Linux app, you can press alt, then > Help > About 1Password, and you'll find your current version there. I hope this is helpful for your purposes!
