-## Prerequisites
+## 📝 Project description
 
-- .NET 6 SDK
+> 🖥️ An MVVM WPF application (.NET 8) providing an Excel-like editor for the `contatos` table in PostgreSQL
-- PostgreSQL database with table:
 
-      ```sql
-      CREATE TABLE public.contatos (
-          ramal text PRIMARY KEY NOT NULL,
-          nome text NOT NULL,
-          email text,
-          area text,
-          aniversario date,
-          "isComando" boolean NOT NULL
-      );
-      ```
-## Setup
-1. Edit appsettings.json, set your ConnectionStrings:ContatosDb.
-2. In a terminal:
-	```bash
-	dotnet restore
-	dotnet build
-	dotnet run --project BackgroundBuilder.csproj
-	```
-3. The main window will appear; on load it fetches and displays all contatos.
-
-## Architecture
-- MVVM with MVVM with ObservableObject, RelayCommand.
-- DI via Microsoft.Extensions.Hosting.
-- Repositories (PostgresContatoRepository) handle all DB I/O with Dapper.
-- Services (DatabaseService) manage the Npgsql connection.
-- ViewModels free of data-access logic: only orchestration.
 ---

+## 🚀 Releases
+
+### 📆 21/05/2025: 🆕 Background & Export Features
+
+- 🎨 **Select Background…**  
   Opens a file picker—choose any image (PNG, JPG, BMP). That image becomes your canvas.
 
-- **Create Image…**  
+- 🖼️ **Create Image…**  
   Saves the current DataGrid overlaid on the background as a single PNG.  
   Uses WPF’s `RenderTargetBitmap` and `PngBitmapEncoder` under the hood.

-## Prerequisites
+## 📝 Project description
 
-- .NET 6 SDK
+> 🖥️ An MVVM WPF application (.NET 8) providing an Excel-like editor for the `contatos` table in PostgreSQL
-- PostgreSQL database with table:
 
-      ```sql
-      CREATE TABLE public.contatos (
-          ramal text PRIMARY KEY NOT NULL,
-          nome text NOT NULL,
-          email text,
-          area text,
-          aniversario date,
-          "isComando" boolean NOT NULL
-      );
-      ```
-## Setup
-1. Edit appsettings.json, set your ConnectionStrings:ContatosDb.
-2. In a terminal:
-	```bash
-	dotnet restore
-	dotnet build
-	dotnet run --project BackgroundBuilder.csproj
-	```
-3. The main window will appear; on load it fetches and displays all contatos.
-
-## Architecture
-- MVVM with MVVM with ObservableObject, RelayCommand.
-- DI via Microsoft.Extensions.Hosting.
-- Repositories (PostgresContatoRepository) handle all DB I/O with Dapper.
-- Services (DatabaseService) manage the Npgsql connection.
-- ViewModels free of data-access logic: only orchestration.
 ---

+### 📆 21/05/2025: 🆕 Background & Export Features
+
+- 🎨 **Select Background…**  
   Opens a file picker—choose any image (PNG, JPG, BMP). That image becomes your canvas.
 
-- **Create Image…**  
+- 🖼️ **Create Image…**  
   Saves the current DataGrid overlaid on the background as a single PNG.  
   Uses WPF’s `RenderTargetBitmap` and `PngBitmapEncoder` under the hood.
