+# LNbits Extension Starter Template
 
-<small>For more about LNBits extension check [this tutorial](https://github.com/lnbits/lnbits/wiki/LNbits-Extensions)</small>
+A **starter template for developers** to build new LNbits extensions with a clean, well-structured foundation.
 
-<h2>*tagline*</h2>
-This is an example extension to help you organise and build you own.
+This repository provides a ready-to-use extension skeleton that follows LNbits conventions and best practices, making it easier to build, test, and maintain custom extensions.

-<h2>If your extension has API endpoints, include useful ones here</h2>
+## Purpose
 
-<code>curl -H "Content-type: application/json" -X POST https://YOUR-LNBITS/YOUR-EXTENSION/api/v1/EXAMPLE -d '{"amount":"100","memo":"example"}' -H "X-Api-Key: YOUR_WALLET-ADMIN/INVOICE-KEY"</code>
+This template is designed to:
+
+- Serve as a **clonable base structure** for new LNbits extensions
+- Demonstrate **recommended LNbits extension patterns**
+- Reduce setup time for new extension projects
+- Encourage consistency across the LNbits extension ecosystem
+
+It is the **recommended starting point** if you want to develop your own LNbits extension with proper structure and conventions.
+
+## Features
+
+The template includes:
+
+- Example extension layout (backend + frontend)
+- Sample database models
+- Example API endpoints
+- Configuration and metadata files
+- Support for **symbolic linking** to simplify local development
+- Clear separation of logic, views, and API routes
+
+All components are intentionally minimal and meant to be adapted or extended.
+
+## API Example
+
+If your extension exposes API endpoints, document them clearly.  
+Below is a simple example request pattern:
+
+```
+curl -H "Content-type: application/json" \
+  -H "X-Api-Key: YOUR_WALLET_ADMIN_OR_INVOICE_KEY" \
+  -X POST https://YOUR-LNBITS/YOUR-EXTENSION/api/v1/example \
+  -d '{"amount": 100, "memo": "example"}'
+```
+
+Replace the endpoint, payload, and permissions according to your extension logic.
+
+## Development Notes
+
+* This template supports **symbolic linking** for local LNbits development setups
+* Intended for developers familiar with LNbits and its extension system
+* You are expected to modify, remove, or extend all example logic
+
+### Important
+
+If you are using **LLMs to generate code**, please make sure to follow the official LNbits instructions when configuring your model to avoid insecure or incompatible output.
