+# Lambda Triggers Sample
+
+A sample app demonstrating an end-to-end mobile workflow using [.NET MAUI](https://learn.microsoft.com/en-us/dotnet/maui/?view=net-maui-7.0), + [Serverless AWS Lambda](https://docs.aws.amazon.com/lambda/latest/dg/lambda-csharp.html) + [AWS S3 Storage](https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/csharp_s3_code_examples.html) in C#.
+
+This sample demonstrates how to use AWS Lambda's [HTTP API Gateway Triggers](https://aws.amazon.com/blogs/developer/deploy-an-existing-asp-net-core-web-api-to-aws-lambda/) + [S3 Triggers](https://docs.aws.amazon.com/lambda/latest/dg/with-s3-example.html) to automatically generate thumbnails of an uploaded image from a mobile app.
+
+1. The .NET MAUI mobile app captures a photo
+2. The .NET MAUI mobile app uploads photo to AWS via an AWS Lambda using an API Gateway HTTP trigger
+3. The AWS Lambda API Gateway Function saves the image to AWS S3 Storage
+4. An AWS Lambda S3 Trigger automatically generates a downscaled thumbnail of the image and saves the thumbnail image back to S3 Storage
+5. The .NET MAUI mobile app retrives the thumbnail image via an AWS Lambda using an API Gateway HTTP trigger and displays it on screen
