+# Hugging Face Space Setup Guide
+
+## Step 1: Create the Hugging Face Space
+
+1. Go to https://huggingface.co/new-space
+
+2. Fill in the details:
+   - **Owner:** richardyoung (your HF username)
+   - **Space name:** `2pac`
+   - **License:** MIT
+   - **Select the SDK:** Gradio
+   - **SDK version:** gradio 4.44.0 (or latest)
+   - **Space hardware:** CPU basic - free (sufficient for this app)
+   - **Visibility:** Public
+
+3. Click **"Create Space"**
+
+## Step 2: Configure the Space
+
+After creating the Space, you'll be on the Space page. You need to copy the README_SPACE.md content to README.md:
+
+```bash
+# In the 2pac repository
+cd ~/2pac
+cp README_SPACE.md README.md
+git add README.md
+git commit -m "Add Hugging Face Space README"
+git push origin main
+```
+
+## Step 3: Push Code to Hugging Face
+
+### Option A: Link GitHub Repository (Recommended - Auto-sync)
+
+1. On your Hugging Face Space page, go to **Settings** (gear icon)
+2. Scroll to **"Git repository"** section
+3. Click **"Link to GitHub"**
+4. Authorize Hugging Face to access your GitHub
+5. Select repository: `ricyoung/2pac`
+6. Select branch: `main`
+7. Click **"Link repository"**
+
+This will automatically sync your GitHub repo to HF Space on every push!
+
+### Option B: Manual Git Push
+
+```bash
+cd ~/2pac
+
+# Add HF Space as a remote (get your token from https://huggingface.co/settings/tokens)
+git remote add space https://richardyoung:[YOUR_HF_TOKEN]@huggingface.co/spaces/richardyoung/2pac
+
+# Push to HF Space
+git push space main
+```
+
+## Step 4: Set Up GitHub Secret for Auto-Sync
+
+If you used Option A (GitHub link), you still need to add the secret for the GitHub Action:
+
+1. Go to https://huggingface.co/settings/tokens
+2. Click **"New token"**
+3. Name: `GitHub Auto-Sync`
+4. Type: **Write** access
+5. Click **"Generate a token"**
+6. **Copy the token** (you won't see it again!)
+
+7. Go to your GitHub repository: https://github.com/ricyoung/2pac/settings/secrets/actions
+8. Click **"New repository secret"**
+9. Name: `HF_TOKEN`
+10. Value: *paste your Hugging Face token*
+11. Click **"Add secret"**
+
+## Step 5: Verify the Space is Running
+
+1. Go to https://huggingface.co/spaces/richardyoung/2pac
+2. Wait for the Space to build (first build takes 2-3 minutes)
+3. You should see the Gradio interface with 3 tabs
+4. Test each tab to ensure everything works:
+   - **Hide Data:** Upload an image and hide text
+   - **Detect:** Analyze an image for steganography
+   - **Extract:** Try extracting from the image you just created
+   - **Check Corruption:** Validate an image
+
+## Step 6: Test Auto-Sync (Optional)
+
+Make a small change to test the auto-sync:
+
+```bash
+cd ~/2pac
+echo "# Test update" >> app.py
+git add app.py
+git commit -m "Test auto-sync"
+git push origin main
+```
+
+Check GitHub Actions: https://github.com/ricyoung/2pac/actions
+
+You should see the workflow running, and the HF Space will update automatically!
+
+## Common Issues
+
+### Space won't build
+- **Check logs** in the Space's "Logs" tab
+- **Common issue:** Missing dependencies in requirements.txt
+- **Solution:** The requirements.txt should have all needed packages
+
+### GitHub Action fails
+- **Check:** Is `HF_TOKEN` secret set correctly?
+- **Check:** Does the token have write access?
+- **Solution:** Regenerate token with write access and update secret
+
+### 404 Error on Space
+- **Wait:** First build takes time
+- **Check:** Is the Space name exactly `2pac`?
+- **Check:** Is your username `richardyoung`?
+
+## Expected URLs
+
+Once set up, your Space will be available at:
+
+- **Space URL:** https://huggingface.co/spaces/richardyoung/2pac
+- **Direct App URL:** https://richardyoung-2pac.hf.space
+- **Embed URL:** Use `https://richardyoung-2pac.hf.space` in iframes
+
+## Next Steps
+
+After the Space is running:
+1. Copy the embed URL: `https://richardyoung-2pac.hf.space`
+2. Continue to integrate it into demo.deepneuro.ai (next task)
