+## General
+
+* Make only high confidence suggestions when reviewing code changes.
+* Always use the latest version C#, currently C# 13 features.
+* Never change global.json unless explicitly asked to.
+* Never change package.json or package-lock.json files unless explicitly asked to.
+
+## Formatting
+
+* Apply code-formatting style defined in `.editorconfig`.
+* Prefer file-scoped namespace declarations and single-line using directives.
+* Insert a newline before the opening curly brace of any code block (e.g., after `if`, `for`, `while`, `foreach`, `using`, `try`, etc.).
+* Ensure that the final return statement of a method is on its own line.
+* Use pattern matching and switch expressions wherever possible.
+* Use `nameof` instead of string literals when referring to member names.
+* Ensure that XML doc comments are created for any public APIs. When applicable, include `<example>` and `<code>` documentation in the comments.
+
+### Nullable Reference Types
+
+* Declare variables non-nullable, and check for `null` at entry points.
+* Always use `is null` or `is not null` instead of `== null` or `!= null`.
+* Trust the C# null annotations and don't add null checks when the type system says a value cannot be null.
+
+### Testing
+
+* We use xUnit SDK v3 for tests.
+* Do not emit "Act", "Arrange" or "Assert" comments.
+* Use Moq for mocking in tests.
+* Copy existing style in nearby files for test method names and capitalization.
+
+## Running tests
+
+* To build and run tests in the repo, use the `build.sh` script that is located in each subdirectory within the `src` folder. For example, to run the build with tests in the `src/Http` directory, run `./src/Http/build.sh -test`.

 ## Manually saving solution and solution filter files
-VS is pretty good at keeping the files up to date and organized correctly. It will also prompt you if it finds an error and, in most cases, offer a solution to fix the issue. Sometimes just saving the file will trigger VS to resolve any issues automatically. However, if you would like to add a new solution filter file or update one manually you can find a tutorial link [here](https://learn.microsoft.com/visualstudio/ide/filtered-solutions).
