+# 
+# Usage:
+#
+# 1 - Set some regex filter for `find` with `REGEX="..."`. Examples:
+# ```
+# REGEX=".*\.\(go\|rs\|js*\|ts*\|md\)"   # Go, Rust, JS, TS, Markdown
+# REGEX=".*\.\(go\|rs\|md\)"             # Go, Rust, Markdown
+# ```
+#
+# 2 - Run the script with REGEX as an env var.
+# ```
+# REGEX=$REGEX bash wc-find.sh
+# ```
+
+echo "REGEX: $REGEX"
