 ## Installing

 ```
 
 ## Usage
-Once you have a businesshours file, run `nowopen [-p] [tag1 tag2...]`. Establishments
-matching any of the specified tags (prefix matching is used) and the amount of
-time till they close will be displayed. E.g. `nowopen plumber` will show how long
-"Mario Bros Plumbing" is open. The "-p" flag can be used to print plain text to
-stdout instead of displaying in a temporary display with colors.
