+# Bob
+
+Bob is a lackadaisical teenager. In conversation, his responses are very limited.
+
+Bob answers 'Sure.' if you ask him a question.
+
+He answers 'Whoa, chill out!' if you yell at him.
+
+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.
+
+## Running tests
+
+Execute the tests with:
+
+```bash
+$ mix test
+```
+
+### Pending tests
+
+In the test suites, all but the first test have been skipped.
+
+Once you get a test passing, you can unskip the next one by
+commenting out the relevant `@tag :pending` with a `#` symbol.
+
+For example:
+
+```elixir
+# @tag :pending
+test "shouting" do
+  assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
+end
+```
+
+Or, you can enable all the tests by commenting out the
+`ExUnit.configure` line in the test suite.
+
+```elixir
+# ExUnit.configure exclude: :pending, trace: true
+```
+
+If you're stuck on something, it may help to look at some of
+the [available resources](https://exercism.io/tracks/elixir/resources)
+out there where answers might be found.
