# Revision History

## 📌 Overview

Quinn automatically saves your course edits as you work. Every change — slide edits, block rearrangements, voiceover updates — is captured as a version snapshot with a 10-second debounce, so you never lose progress. You can browse previous versions, preview what changed, and restore any earlier version at any time.

## ✅ Step-by-Step Instructions

### Step 1: Open the Course Editor

Navigate to **Courses**, select the course you want to review, and click **Edit Course** to open it in the editor.

### Step 2: Open Version History

Click the **⋯** (more options) menu in the top-right corner of the editor toolbar. Select **Revision History** from the dropdown menu. A full-screen panel will open.

### Step 3: Browse Versions

The right sidebar shows a chronological list of all saved versions, grouped by date. Each entry displays:

- The **time** the version was saved
- The **name** of the person who made the edit
- A **"Current version"** label on the version that matches your live course

### Step 4: Preview a Version

Click on any version in the list to preview it in the main content area. The preview shows the full course content as it existed at that point in time.

### Step 5: Compare Changes

When viewing a version, you can see a diff of what changed between that version and the current live version. Added, removed, and modified blocks are highlighted so you can quickly understand what was different.

### Step 6: Restore a Version

If you want to go back to a previous version, click the **Restore this version** button at the top of the preview. The course will immediately revert to that version's content. The restored version becomes the new current version and a new entry is added to the history.

💡 Tip: Restoring a version doesn't delete any history — you can always restore back to any version, including the one you had before restoring.

## 💡 Tips

- Quinn auto-saves your work every 10 seconds after your last edit — no need to manually save.

- Duplicate snapshots are automatically filtered out, so you won't see redundant entries if nothing changed.

- You can open Version History at any time, even while actively editing — your unsaved changes won't be lost.

- All team members' edits are tracked, so you can see who changed what and when.
