+      gmap helps you understand your Git repository at a glance — not
+      just what changed, but when, how much, and by whom. Visualize
+      commit activity over time, spot churn-heavy files, explore
+      contributor dynamics, and more — all from your terminal.
+
+      Built for developers who live in the CLI and want quick,
+      powerful insights.
