   <ul>
     <li>
-      <strong>Concepts</strong> — Understand how Git actually works: objects,
-      references, branching, merging, conflict resolution, and branching strategies.
+      <strong>How Git works</strong> — the workspace, index, and repository
+      pipeline that every command builds on.
+    </li>
+    <li>
+      <strong>Building blocks</strong> — objects, references, HEAD, and how
+      Git stores your project history internally.
     </li>
     <li>
-      <strong>Operations</strong> — Master 30+ Git commands organized by workflow:
-      create, track, branch, sync, revert, and inspect.
+      <strong>Branching and merging</strong> — work on features in isolation,
+      merge strategies, conflict resolution, cherry-pick, rebase, and stash.
     </li>
     <li>
-      <strong>Test yourself</strong> — 96 quiz questions to validate your
-      understanding and prepare for technical interviews.
+      <strong>Remote collaboration</strong> — clone, push, pull, fetch, and
+      forking workflows for team projects.
     </li>
     <li>
-      <strong>Reference</strong> — Git dictionary, cheat sheets, client tools,
-      and curated external resources.
+      <strong>Expert topics</strong> — configuration, selectors, refspecs,
+      hooks, bisect, and history rewriting.
