 # Grounds for Support
 
-⚠️ Under Construction ⚠️
+Grounds for Support is a full-stack web application designed to facilitate donations ("buying a coffee") using Stripe. It demonstrates a modern integration of a React frontend with an ASP.NET Core backend, handling secure payments, webhooks, and data persistence.
 
-This is a simple application I built to help me better understand how to intergrate Stripe so that I can accept payments from people over the interwebz.
+## 🚀 Features
 
+- **Secure Donations**: Integrated with Stripe Payment Intents for secure transaction processing.
+- **Custom Amounts**: Users can specify their donation amount, name, and a personal message.

+## Getting Started
+
+### Prerequisites
+
+- .NET SDK
+- Node.js
+- Stripe Account (for API keys)
+
+### Local Development
+
+1. **Clone the repository**
+
+    ```bash
+    git clone https://github.com/StevanFreeborn/groundsforsupport.stevanfreeborn.com.git
+    cd groundsforsupport.stevanfreeborn.com
+    ```
+
+2. **Configure Environment**
+    - Update `src/GroundsForSupport.Server/appsettings.Development.json` (or use User Secrets) with your Stripe keys:
+
+        ```json
+        "StripeOptions": {
+          "ApiKey": "sk_test_...",
+          "EventsWebhookSecret": "whsec_..."
+        }
+        ```
+
+    - Create a `.env` file in `src/GroundsForSupport.Client` with your publishable key:
+
+        ```txt
+        VITE_STRIPE_API_KEY=pk_test_...
+        ```
+
+3. **Run the Application**
+    The server project is configured to build the client automatically.
+
+    ```bash
+    cd src/GroundsForSupport.Server
+    dotnet run
+    ```
+
+    The API will be available at `https://localhost:7071` (or similar), and it will serve the static frontend files.
+
+    *Alternatively, run frontend separately for hot-reloading:*
+
+    ```bash
+    cd src/GroundsForSupport.Client
+    npm install
+    npm run dev
+    ```
+
+## Testing
+
+- **Frontend Tests**:
+
+    ```bash
+    cd src/GroundsForSupport.Client
+    npm test
+    ```
+
+- **Backend Tests**:
+
+    ```bash
+    dotnet test
+    ```
