+
+## Running the tests
+
+Execute the tests with:
+
+```bash
+$ yarn test
+```
+
+## Skipped tests
+
+In the test suites all tests but the first have been skipped.
+
+Once you get a test passing, you can enable the next one by changing `xit` to
+`it`.
+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit bob.ts` 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:

+# Bob
+
+Welcome to Bob on Exercism's TypeScript Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+Bob is a lackadaisical teenager. In conversation, his responses are very limited.
+
+Bob answers 'Sure.' if you ask him a question, such as "How are you?".
+
+He answers 'Whoa, chill out!' if you YELL AT HIM (in all capitals).
+
+He answers 'Calm down, I know what I'm doing!' if you yell a question at him.
+
+He says 'Fine. Be that way!' if you address him without actually saying
+anything.
+
+He answers 'Whatever.' to anything else.
+
+Bob's conversational partner is a purist when it comes to written communication and always follows normal rules regarding sentence punctuation in English.
