+## Development
+
+### External Requirements
+
+In order to run the project you first have to install:
+
+- [ASP.NET Core 7](https://learn.microsoft.com/en-us/aspnet/core/introduction-to-aspnet-core?view=aspnetcore-7.0)
+- [PostgreSQL](https://www.postgresql.org/download/)
+
+### Postgres Setup
+
+Install and start the database by installing Docker and running the following command.
+
+```
+docker run --name postgres-490 -e POSTGRES_DB=fu_dev -e POSTGRES_PASSWORD=dev -e POSTGRES_USER=dev -p 5432:5432 postgres:alpine
+```
+
+To run the container at a later time, run:
+
+```
+docker container start postgres-490
+```
+
+Alternatively, install and start a PostgreSQL database manually.
+
+### Config Setup
+
+Config settings are loaded from the environment variables. To automatically load the environment variable from a file, create a `.env` file in this folder.
+
+#### Blob storage
+
+An azure storage account is needed with a storage container. Public anonymous access must be enabled. The `STORAGE_CONNECTION_STRING` and `AVATAR_CONTAINER_NAME` environment variables must be set.
+
+```
+STORAGE_CONNECTION_STRING="XXXXXXXX"
+AVATAR_CONTAINER_NAME="some-container-name"
+```
+
+#### Jwt Secret
+
+A random string of 32+ characters is required in the `JWT_SECRET` environment variable as a Jwt Secret.
+
+```
+JWT_SECRET="my-32-character-ultra-secure-and-ultra-long-secret"
+```
+
+#### Email service
+
+An azure communication service is needed to send emails.
+
+```
+EMAIL_CONNECTION_STRING="XXXXXXXX"
+```
+
+#### Connect to Postgres
+
+Set the postgres `CONNECTION_STRING` environment variable.
+
+```
+CONNECTION_STRING="Host=localhost; Database=fu_dev; Username=dev; Password=dev"
+```
+
+### Coding Style
+
+Follow Google's C# [style guide](https://google.github.io/styleguide/csharp-style.html)
+
+## Testing
+
+Run tests on the backend with `dotnet test`. Tests are located in `FU.API.Tests/`. They consist of service unit tests as behavioral testing is done by the SPA.

 First an avatar is uploaded to the server via `AvatarController.UploadAvatar`. Then it is validated to be an image, cropped to be square, resized, and converted to a JPEG using the `SkiaSharp` library. Then the image is uploaded to a public azure storage blob and its a url is returned to the user for previewing. If the user wants to use the image, they call `UsersController.UpdateProfile` to set it as their new avatar. After awhile, unused profile pictures are deleted by `PeriodicRemoteStorageCleanerHostedService`.

+
+In this example, UserSearchRequestDTO is a DTO used for handling user search requests. It contains properties for keywords, sorting criteria, pagination limits, and page numbers. The [FromQuery] attribute indicates that the properties should be bound from the query string when used in our ASP.NET Web API.
 
-#### Jwt Secret
-
-A random string of 32+ characters is required in the `JWT_SECRET` environment variable as a Jwt Secret.
+To process the user search request, a static mapper class is utilized to convert the UserSearchRequestDTO to a UserQuery. Here's an example of how it's done:
 
 ```
-JWT_SECRET="my-32-character-ultra-secure-and-ultra-long-secret"
-```
