+"""
+Main entry point for the AI Fluency Plan project.
+
+This script demonstrates how to load and display a personal AI fluency plan that is stored in ``plan.txt``.
+It also provides three example usages:
+1. Print the entire plan.
+2. Show only the first 5 lines of the plan.
+3. Count the number of words in the plan.
+
+The goal of this repository is to showcase a simple, well‑structured Python project that can be used as a template for future assignments.
