+# Coloring Scripts
+
+### Definition
+
+These scripts are used to demonstrate the `ansi` command using `ansi` coloring. This is mainly a demo area where we have taken typical `bash` scripts and ported them to nushell scripts. It would be nice if all scripts here showed the "other" version of script and the ported nushell version. We can show "other" flavors of scripts by including them as comments in the nushell scripts or by naming the nushell script and the other script the same basename.

+# Prompt Scripts
