+# Help
+
+## Running the tests
+
+You can run the tests by opening a command prompt in the exercise's directory, and then running the [`dotnet test` command](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-test)
+Alternatively, most IDE's have built-in support for running tests, including [Visual Studio](https://docs.microsoft.com/en-us/visualstudio/test/run-unit-tests-with-test-explorer), [Rider](https://www.jetbrains.com/help/rider/Unit_Testing_in_Solution.html) and [Visual Studio code](https://github.com/OmniSharp/omnisharp-vscode/wiki/How-to-run-and-debug-unit-tests).
+See the [tests page](https://exercism.org/docs/tracks/csharp/tests) for more information.
+
+## Skipped tests
+
+Initially, only the first test will be enabled.
+This is to encourage you to solve the exercise one step at a time.
+Once you get the first test passing, remove the `Skip` property from the next test and work on getting that test passing.
+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit HelloWorld.cs` command.
+This command will upload your solution to the Exercism website and print the solution page's URL.
+
+It's possible to submit an incomplete solution which allows you to:
+
+- See how others have completed the exercise
+- Request help from a mentor
+
+## Need to get help?
+
+If you'd like help solving the exercise, check the following pages:
+
+- The [C# track's documentation](https://exercism.org/docs/tracks/csharp)
+- The [C# track's programming category on the forum](https://forum.exercism.org/c/programming/csharp)
+- [Exercism's programming category on the forum](https://forum.exercism.org/c/programming/5)
+- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
+
+Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
+
+To get help if you're having trouble, you can use one of the following resources:
+
+- [/r/csharp](https://www.reddit.com/r/csharp) is the C# subreddit.
+- [StackOverflow](http://stackoverflow.com/questions/tagged/c%23) can be used to search for your problem and see if it has been answered already. You can also ask and answer questions.

+# Hello World
+
+Welcome to Hello World on Exercism's C# Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+The classical introductory exercise.
+Just say "Hello, World!".
+
+["Hello, World!"][hello-world] is the traditional first program for beginning programming in a new language or environment.
+
+The objectives are simple:
+
+- Modify the provided code so that it produces the string "Hello, World!".
+- Run the test suite and make sure that it succeeds.
+- Submit your solution and check it at the website.
+
+If everything goes well, you will be ready to fetch your first real exercise.
