GitLab was one of the first all remote workforce companies. One of the great practices of GitLab is the README file.
Every employee at GitLab creates their own README file. It can be as short or as long you like, but it is meant to provide information to coworkers on the best way to work with you.
It might include your normal hours (updated to reflect any changes to it), the best way to contact you, or just things about your style. It can even be things about you personally (hobbies, family, etc.).
The point is that before reaching out to someone, you can learn about them. You can customize your communication specifically for them. It enables a remote workforce to get personal.
I've sometimes referred to this as a User Manual on You. The same concept. It lets you have some say in how people communicate with you.
