+The '${exerciseName}' exercise has been created in '${exerciseDir}'.
 Your next steps are:
 - Check the test suite in $($files.test | Join-String -Separator ",")
   - If the tests need changes, update the '${exerciseName}' class in the '${generator}' file
     and then run: 'dotnet run --project generators --exercise ${Exercise}'
-- Any test cases you don't implement, mark them in 'exercises/practice/${slug}/.meta/tests.toml' with "include = false"
-- Create the example solution in $($files.example | Join-String -Separator ",")
-- Verify the example solution passes the tests by running 'bin/verify-exercises ${slug}'
-- Create the stub solution in $($files.solution | Join-String -Separator ",")
