-## Troubleshooting
-
-### "Empty Revert / No Changes"
-
-**Problem:** Revert doesn't seem to do anything.
-
-**Possible causes:**
-- Commit was already reverted
-- Subsequent commits already undid the changes
-- Wrong commit hash
-
-**Solution:**
-```pwsh
-# Check what the commit actually changed
-git show <commit-hash>
-
-# Check if already reverted
-git log --grep="Revert"
-```
-
-### "Conflicts During Revert"
-
-**Problem:** Revert causes merge conflicts.
-
-**Why:** Subsequent commits modified the same code.
-
-**Solution:**
-1. Manually resolve conflicts in affected files
-2. `git add <resolved-files>`
-3. `git revert --continue`
-
-Or consider fixing forward with a new commit instead of reverting.
-
-### "Reverting Old Commit Breaks Something"
-
-**Problem:** After reverting an old commit, something else stops working.
-
-**Why:** The old commit might have been a dependency for later commits.
-
-**Solution:** 
-1. Check what changed: `git diff HEAD~1 HEAD`
-2. Either fix the issue with a new commit, or
-3. Revert the revert if needed: `git revert <revert-commit-hash>`
-
-## Advanced: Revert Internals
-
-Understanding what revert does under the hood:
-
-```pwsh
-# Revert creates a new commit with inverse changes
-git revert <commit-hash>
-
-# This is equivalent to:
-git diff <commit-hash>^..<commit-hash> > changes.patch
-patch -R < changes.patch  # Apply in reverse
-git add .
-git commit -m "Revert '<original message>'"
-```
-
-**Key insight:** Revert computes the diff of the target commit, inverts it, and applies it as a new commit.
-
-## Going Further
-
-Now that you understand revert, you're ready for:
-
-- **Module 06: Git Reset** - Learn the dangerous but powerful local history rewriting
-- **Module 07: Git Stash** - Temporarily set aside uncommitted changes
-- **Module 08: Multiplayer Git** - Collaborate with advanced workflows
-
-## Summary
-
-You've learned:
-
-- ✅ `git revert` creates new commits that undo previous changes
-- ✅ Revert is safe for shared/pushed commits
-- ✅ Commits before and after the reverted commit are preserved
-- ✅ Multiple commits can be reverted in one command
-- ✅ Revert preserves complete history for audit trails
-
-**The Golden Rule of Revert:** Use revert for any commit that might be shared with others.
-
-## Next Steps
-
-1. Complete both challenge scenarios
-2. Run `.\verify.ps1` to check your solutions
-3. Experiment with reverting different commits
-4. Move on to Module 07: Git Reset (dangerous but powerful!)
