+# About:
+# This is a helper script to tag and push a new release.
+# GitHub Actions use release tags to allow users to select a specific version of the action to use.
+# This script will do the following:
+# 1. Get the latest release tag
+# 2. Prompt the user for a new release tag (while displaying the latest release tag, and a regex to validate the new tag)
+# 3. Tag the new release
+# 4. Push the new tag to the remote
+
+# Usage:
+# script/release
+
+# COLORS
+OFF='\033[0m'
+RED='\033[0;31m'
