+  timeout: "2s"            # Check timeout
+  method: "data-transfer"  # tcp-dial or data-transfer
+  maxConnectionAge: "25m"  # Reconnect before k8s timeout
+  maxIdleTime: "10m"       # Detect idle connections
+
+reliability:
+  tcpKeepalive: "30s"
+  dialTimeout: "30s"
+  retryOnStale: true
+```
+
+Health check methods:
+- `tcp-dial` - Fast TCP connection test
+- `data-transfer` - Verifies tunnel functionality by attempting data read
+
+Connection age reconnection only triggers when the connection is also idle, preventing interruption of active transfers like database dumps.
+
+### mDNS Hostnames
+
+Enable mDNS to access forwards via `.local` hostnames:
+
+```yaml
+mdns:
+  enabled: true
+
+contexts:
+  - name: production
+    namespaces:
+      - name: default
+        forwards:
+          - resource: service/postgres
+            port: 5432
+            localPort: 5432
+            alias: prod-db  # Accessible via prod-db.local:5432
+```
+
+- Explicit `alias` becomes `<alias>.local`
+- Without alias, hostname is generated from resource name (`service/redis` → `redis.local`)
+- Works on macOS (Bonjour) and Linux (avahi-daemon)
+
+Verify registration:
+```bash
+dns-sd -B _kportal._tcp local       # macOS
+avahi-browse -t _kportal._tcp       # Linux
+```
+

-## 🔄 kftray Migration
+### Port Conflict Detection

-Migrate from kftray JSON configuration:
+kportal validates port availability at startup and during hot-reload, showing which process is using conflicting ports.
+
+### Retry Strategy
+
+Exponential backoff: 1s → 2s → 4s → 8s → 10s (max). Retries continue indefinitely until connection succeeds.
+
+## Migration from kftray

 ```bash
 kportal --convert configs.json --convert-output .kportal.yaml
 ```

-**Example conversion:**
+## Signal Handling

-kftray JSON:
-```json
-[
-  {
-    "service": "postgres",
-    "namespace": "default",
-    "local_port": 5432,
-    "remote_port": 5432,
-    "context": "production",
-    "workload_type": "service",
-    "protocol": "tcp",
-    "alias": "prod-db"
-  }
-]
-```
-
-Converts to kportal YAML:
-```yaml
-contexts:
-  - name: production
-    namespaces:
-      - name: default
-        forwards:
-          - resource: service/postgres
-            protocol: tcp
-            port: 5432
-            localPort: 5432
-            alias: prod-db
-```
-
-## 🎨 Status Indicators
-
-| Indicator | Status | Description |
-|-----------|--------|-------------|
-| `● Active` | 🟢 Green | Port-forward is active and healthy |
-| `○ Starting` | 🟡 Yellow | Initial connection in progress (10s grace period) |
-| `◐ Reconnecting` | 🟡 Yellow | Attempting to reconnect after failure |
-| `✗ Error` | 🔴 Red | Connection failed - see error details below table |
-| `○ Disabled` | ⚪ Gray | Port-forward manually disabled via Space key |
-
-## 🛠️ Advanced Features
-
-### Hot-Reload
-
-kportal automatically watches for configuration file changes and reloads:
-
-```bash
-# Edit your config while kportal is running
-vim .kportal.yaml
-
-# Changes are applied automatically within seconds:
-# - New forwards are started
-# - Removed forwards are stopped
-# - Existing forwards continue running unchanged
-```
-
-Supports manual reload via `SIGHUP`:
-```bash
-kill -HUP $(pgrep kportal)
-```
-
-### Health Checks
-
-Built-in health monitoring system:
- **Check interval**: Every 5 seconds
- **Timeout**: 2 seconds per check
- **Grace period**: 10 seconds for new connections
- **Automatic updates**: Real-time status changes in UI
- **Error tracking**: Detailed error messages for failed connections
-
-### Error Display
-
-When connections fail, errors are displayed below the table:
-
-```
-Errors:
-  • prod-postgres: dial tcp 127.0.0.1:5432: connect: connection refused
-  • prod-redis: i/o timeout after 2.0s
-```
-
-Errors automatically clear when:
- Connection becomes healthy
- Forward is disabled
- Forward is removed
-
-### Port Conflict Detection
-
-kportal checks for port conflicts at multiple stages:
-
-**At startup:**
-```
-Port conflicts detected:
-  Port 8080:
-    • Requested by: api-server (context: prod, namespace: default)
-    • Currently used by: PID 1234 (chrome)
-```
-
-**During hot-reload:**
- Only validates new ports being added
- Skips currently managed ports
- Rejects configuration if conflicts found
-
-### Pod Restart Handling
-
-When a pod restarts:
-1. Port-forward connection breaks
-2. kportal immediately re-resolves the resource:
-   - For prefix matches: Finds newest pod with matching prefix
-   - For selectors: Re-queries pods with matching labels
-3. Reconnects to new pod
-4. Logs the switch: `Switched to new pod: old-pod-abc → new-pod-xyz`
-
-### Retry Strategy
-
-Exponential backoff with maximum interval:
- **Intervals**: 1s → 2s → 4s → 8s → 10s (max)
- **Infinite retries**: Continues until connection succeeds
- **Independent**: Each forward has its own retry logic
- **Grace period**: First 10 seconds show "Starting" instead of "Error"
-

+- `Ctrl+C` / `SIGTERM` - Graceful shutdown
+- `SIGHUP` - Reload configuration

 ## 🐛 Troubleshooting

 ### Port Already in Use

-**Problem**: `Port 8080: already in use by PID 1234 (chrome)`
-
-**Solutions**:
 ```bash
-# Find the process
-lsof -i :8080
-
-# Kill the process
-kill 1234
-
-# Or use a different local port in config
-local_port: 8081
+lsof -i :<port>
+kill <pid>
 ```

 ### Connection Refused

-**Problem**: `dial tcp 127.0.0.1:8080: connect: connection refused`
-
-**Common causes**:
-1. **Pod not ready yet** - Wait for status to change from "Starting" → "Active" (10s grace period)
-2. **Wrong port number** - Verify the pod/service actually exposes that port
-3. **Service not exposed** - Check with `kubectl get svc` and `kubectl describe svc <name>`
-
-**Debug**:
-```bash
-# Check pod status
-kubectl get pods -n <namespace>
-
-# Check if port is exposed
-kubectl describe pod <pod-name> -n <namespace>
-
-# Check service endpoints
-kubectl get endpoints <service-name> -n <namespace>
-```
+1. Verify pod is running: `kubectl get pods -n <namespace>`
+2. Verify port is correct: `kubectl describe pod <pod>`
+3. Check service endpoints: `kubectl get endpoints <service>`

 ### Context Not Found

-**Problem**: `context "prod" not found in kubeconfig`
-
-**Solution**:
 ```bash
-# List available contexts
 kubectl config get-contexts
-
-# Verify context name matches
-kubectl config current-context
-
-# Update your config to use the correct context name
 ```

-### Health Check Errors During Startup
+## 🔧 Development

-**Problem**: Seeing "Error" status immediately after starting
+### Prerequisites

-**This is normal!** kportal has a 10-second grace period. If the connection is still failing after 10 seconds, check:
- Pod is running: `kubectl get pods`
- Port is correct in config
- Network connectivity to cluster
+- Go 1.23+
+- Kubernetes cluster access
+- kubectl configured

-### Logs Covering UI
+### Build

-**Problem**: Kubernetes client logs appearing over the interactive UI
-
-**This is fixed in v0.1.5+**. The interactive mode now completely suppresses all logs including:
- Standard Go `log` package
- Kubernetes `klog` output
- Any stderr/stdout leakage
-
-If you still see logs, please file an issue!

-## 🔒 Required GitHub Secrets
-
-For full automation, set these secrets in your GitHub repository:
-
-1. **GITHUB_TOKEN** - Automatically provided by GitHub Actions
-2. **HOMEBREW_TAP_TOKEN** - Personal access token for updating Homebrew tap
-   - Create at: https://github.com/settings/tokens
-   - Permissions needed: `repo` scope
-   - Add to repository secrets
-
-## 📝 Next Steps
-
-### 1. Enable GitHub Pages
- Repository Settings → Pages → Source: main branch, /docs folder
-
-### 2. Create Homebrew Tap Repository
-```bash
-# Create new repository
-gh repo create lukaszraczylo/brew-taps --public
-
-# Clone and set up
-git clone https://github.com/lukaszraczylo/brew-taps
-cd brew-taps
-cp ../kportal/Formula/kportal.rb ./Formula/
-git add Formula/kportal.rb
-git commit -m "Initial formula for kportal"
-git push origin main
-```
-
-### 3. Add GitHub Token to Secrets
- Repository Settings → Secrets and variables → Actions
- New repository secret
- Name: `HOMEBREW_TAP_TOKEN`
- Value: Your personal access token
-
-### 4. Create First Release
-```bash
-cd kportal
-git add .
-git commit -m "feat: initial release setup"
-git push origin main
-git tag -a v0.1.5 -m "Release v0.1.5"
-git push origin v0.1.5
-```
-
-### 5. Test Installation Methods
-
-After first release, test:
-```bash
-# Homebrew (once tap is set up)
-brew install lukaszraczylo/tap/kportal
-
-# Quick install script
-curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/kportal/main/install.sh | bash
-
-# Manual download
-# Visit releases page and download binary
-```
-
-## 🎨 Customization
-
-### Update Website Colors
-
-Edit `docs/index.html`:
-```javascript
-tailwind.config = {
-    theme: {
-        extend: {
-            colors: {
-                primary: '#3b82f6',    // Blue
-                secondary: '#8b5cf6',   // Purple
-                dark: '#0f172a',        // Dark slate
-            }
-        }
-    }
-}
-```
-
-### Update Release Notes Template
-
-Edit `.github/workflows/release.yml` in the "Generate release notes" step.
-
-## 📊 Monitoring
-
-After releases, monitor:
- GitHub Actions workflow runs
- GitHub Releases page
- Homebrew tap repository commits
- Download statistics on releases page
-
-## 🐛 Troubleshooting
-
-### Release workflow fails
- Check GitHub Actions logs
- Verify all required secrets are set
- Ensure tag follows v\d+.\d+.\d+ format
-
-### Homebrew formula not updating
- Verify HOMEBREW_TAP_TOKEN is valid
- Check tap repository permissions
- Review release workflow logs
-
-### Install script fails
- Test locally with different OS/arch combinations
- Check release binary naming matches script expectations
- Verify binaries are attached to release
-
-## ✅ Checklist for First Release
-
- [ ] All code committed and pushed
- [ ] GitHub Pages enabled
- [ ] Homebrew tap repository created
- [ ] HOMEBREW_TAP_TOKEN secret set
- [ ] CHANGELOG.md updated

+# Interactive Wizards
+
+kportal includes wizards for adding and removing port forwards from the running UI.
+
+## ⌨️ Quick Reference
+
+| Key | Action |
+|-----|--------|
+| `a` | Add new forward |
+| `d` | Delete forwards |
+
+## ➕ Add Forward Wizard
+
+Press `a` from the main view to start the wizard.
+
+### Steps
+
+1. **Context** - Select Kubernetes context
+2. **Namespace** - Select namespace
+3. **Resource Type** - Choose pod (prefix), pod (selector), or service
+4. **Resource** - Enter prefix, selector, or select service
+5. **Remote Port** - Enter port on the resource
+6. **Local Port** - Enter local port (validates availability)
+7. **Confirm** - Review and optionally add an alias
+
+### Navigation
+
+| Key | Action |
+|-----|--------|
+| `↑↓` / `j/k` | Navigate options |
+| `Enter` | Confirm and proceed |
+| `Esc` | Go back / Cancel |
+| `Ctrl+C` | Cancel immediately |
+
+## 🗑️ Delete Forward Wizard
+
+Press `d` from the main view.
+
+### Navigation
+
+| Key | Action |
+|-----|--------|
+| `↑↓` / `j/k` | Navigate |
+| `Space` | Toggle selection |
+| `a` | Select all |
+| `n` | Deselect all |
+| `Enter` | Confirm deletion |
+| `Esc` | Cancel |
+
+## 🎯 Resource Selection
+
+### Pod by Prefix
+
+Enter app name prefix to match pods:
+- `nginx` matches `nginx-deployment-abc123`
+- `postgres` matches `postgres-statefulset-0`
+
+### Pod by Selector
+
+Use Kubernetes label syntax:
+- `app=nginx`
+- `app=nginx,env=prod`
+
+Matching pods are shown in real-time.
+
+### Service
+
+Select from discovered services in the namespace.
+
+## 🔄 Auto Hot-Reload
+
+Changes are applied automatically:
+1. Wizard writes to `.kportal.yaml` atomically
+2. File watcher detects change (~100ms)
+3. Manager reloads and starts forward
+4. UI updates
+
+## Error Handling
+
+The wizards handle:
+- Cluster unreachable - allows manual entry
+- Port conflicts - shows which process is using the port
+- Invalid selectors - real-time validation
+- Duplicate ports - prevents conflicts
+
+## 🐛 Troubleshooting
+
+### Wizard not appearing
+
+Verify cluster connectivity:
+```bash
+kubectl cluster-info
+```
+
+### Port validation delayed
+
+Port checks run asynchronously. Wait briefly after typing.
+
+### Changes not visible
+
+Check:
+1. `.kportal.yaml` was written correctly
+2. No validation errors in file
+3. kportal process is running
