+## Step to implement
+
+### Install/ Add Microsoft.EntityFrameworkCore.Sqlite to Project
+
+```xml
+    <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="9.0.7" />
+```
+
+### Register App db Context before    `var app = builder.Build();` in MauiProgram.cs
+
+```cs
+var dbPath = Path.Combine(FileSystem.AppDataDirectory, "waterreminder.db3");
+
+builder.Services.AddDbContext<AppDbContext>(options => options.UseSqlite($"Filename={dbPath}"));
+```
+
+### Just Before app run add this Command
+
+```cs
+// Initialize the database 
+using (var scope = app.Services.CreateScope())
+{
+    var dbContext = scope.ServiceProvider.GetRequiredService<AppDbContext>();
+    dbContext.Database.EnsureCreated();
+}
+
+return app;
+```
+
+### Create Add Db Context
+
+```cs
+namespace WaterReminder.Data;
+
+public class AppDbContext(DbContextOptions<AppDbContext> options) : DbContext(options)
+{
+    public DbSet<Reminder> Reminders { get; set; }
+}
+```
+
+### Below is service or uses 
+
+```cs
+public class ReminderService : IReminderService
+{
+    private readonly AppDbContext _context;
+
+    public ReminderService(AppDbContext context)
+    {
+        _context = context; 
+    }
+
+    public Task<List<Reminder>> GetRemindersAsync() => _context.Reminders.ToListAsync();
+}
+```
