 
   Mix is the project management and build tool for Elixir. Invoking `mix test`
   from the command line will run tests in each file matching the pattern
-  "*_test.exs" found in the `test` directory of your project.
+  `*_test.exs` found in the `test` directory of your project.
 
   By convention, you could also create a `test_helper.exs` file inside the
   `test` directory and put the code common to all tests there.
 
-  The minimum example of a test_helper.exs file would be:
+  The minimum example of a `test_helper.exs` file would be:
 
       # test/test_helper.exs
       ExUnit.start
 
-  Then, in each test file, require test_helper.exs before defining test modules
+  Then, in each test file, require `test_helper.exs` before defining test modules
   (or cases):
 
       # test/myproject_test.exs

  * `:max_cases` - Maximum number of cases to run in parallel.
                   Defaults to `:erlang.system_info(:schedulers_online)`;

  * `:trace` - Set ExUnit into trace mode, this set `:max_cases` to 1
               and prints each test case and test while running;

  """

      end

  To run the test above, all you need to do is to run the file
  using `elixir` from the command line. Assuming you named your file
  `assertion_test.exs`, you can run it as:

      bin/elixir assertion_test.exs
