+# date.tcl
+
+The script [date.tcl](date.tcl) shows the current date and time with the
+`!date` command.
+
+## Setup
+
+You can enable the `!date` command for a specific channel by setting the
+`date` flag for the channel in your Eggdrop. For example, enable the script in
+the channel `#test` with the following Eggdrop command:
+
+```
+.chanset #test +date
+```
+
+Accordingly, you can disable the `!date` command for a specific channel by
+removing the `date` flag from the channel in your Eggdrop. For example, disable
+the script in the channel `#test` with the following Eggdrop command:
+
+```
+.chanset #test -date
+```
+
