+# V2 Programming Model Example App
+
+This example demonstrates the **V2 attribute-based programming model** for Azure Functions with PowerShell. Functions are defined using PowerShell attributes — no `function.json` files are needed.
+
+## Key Differences from V1
+
+| Feature | V1 (Classic) | V2 (Attribute-based) |
+|---|---|---|
+| Function definition | `function.json` + `run.ps1` per function | `[AzFunction()]` attribute in `.psm1` files |
+| File layout | One folder per function | Functions organized by domain in `.psm1` files |
+| Binding configuration | JSON in `function.json` | Attributes on parameters |
+| Indexing | Host reads `function.json` | Worker indexes via AST parsing |
+
+## Functions Included
+
+### HttpFunctions.psm1
+- **HttpExample** — Anonymous HTTP trigger (GET/POST) with custom route `/hello`
+- **GetAzureVm** — Function-level auth HTTP trigger that fetches an Azure VM
+
+### TimerFunctions.psm1
+- **CleanupJob** — Timer trigger that runs every 6 hours
+
+### QueueFunctions.psm1
+- **ProcessQueueMessage** — Queue trigger with queue output binding
+
+## Running Locally
+
+```powershell
+cd examples/V2App
+func start
+```
+
+## .funcignore
+
+The `.funcignore` file excludes files from deployment (similar to `.gitignore`):
+- `.git*` — Git metadata
+- `.vscode` — Editor settings
+- `local.settings.json` — Local-only settings
+- `test` — Test directories
+- `*.tests.ps1` — Test files
