+# nowopen
+
+`nowopen` is a simple program to display which places are currently open.
+
+## Usage
+
+First, create a file with business hours in it at either `~/.local/share/nowopen/businesshours`
+(recommended) or `~/.businesshours`. An example businesshours file is provided.
+The format looks like:
+
+```
+Mario Bros Plumbing (plumbers):
+    7am-6:30pm
+    sun: closed
+```
+
+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.
