+
+**Status:** Planned for future release

+
+---
+
+## ⚙️ Getting Started
+
+### First-Time Setup
+1. **Create a Profile:**
+   - Click the NostrKey icon
+   - Click **Settings** or **Full Settings**
+   - Click **New Local** to create a local profile, or **New Bunker** for remote signing
+
+2. **Add Your Key:**
+   - **Local Profile:** Paste your `nsec` or hex private key
+   - **Bunker Profile:** Paste your `bunker://` connection URL
+   - Click **Save**
+
+3. **Configure Relays:**
+   - Scroll to the **Relays** section
+   - Add your preferred relays (or use recommended ones)
+   - Set read/write permissions for each
+
+4. **Set Permissions:**
+   - Visit a Nostr web app
+   - When prompted, choose **Allow**, **Deny**, or **Ask** for each permission
+   - Permissions are saved per-app and can be changed in Settings
+
+### Security Best Practices
+- ✅ **Enable Master Password:** Encrypt your keys at rest
+- ✅ **Backup Your Keys:** Export and securely store your `nsec`
+- ✅ **Use Bunker for High Security:** Keep keys off your device entirely
+- ✅ **Review Permissions Regularly:** Check which apps have access
+- ⚠️ **Never Share Your Private Key:** NostrKey will never ask for it outside the extension
+
+---
+
+## 🆘 Common Issues
+
+### "Extension cannot access this page"
+Some browsers restrict extensions on certain pages (like `chrome://` or `about:` pages). This is normal browser security.
+
+### "Failed to connect to relay"
+- Check your internet connection
+- Verify the relay URL is correct (must start with `wss://`)
+- Try a different relay from the recommended list
+
+### "Invalid key format"
+- Ensure you're pasting a valid `nsec` (starts with `nsec1`) or hex key
+- Remove any extra spaces or line breaks
+- For encrypted keys, use the ncryptsec import feature
+
+### Keys not syncing between devices
+- NostrKey stores keys locally in each browser
+- To use the same key on multiple devices, manually import it on each
+- Or use nsecBunker for centralized key management
