-  `setup_all` can return a keyword list, a map, or a tuple in the shape
-  of `{:ok, keyword() | map()}`, the keyword list or map will be merged
-  into the current context and will be available in all subsequent `setup_all`,
-  `setup`, and the `test` itself. For instance, the `conn` from the previous
-  example can be accessed as:
+  The context returned by `setup_all/1` will be available in all subsequent
+  `setup_all`, `setup`, and the `test` itself. For instance, the `conn` from
+  the previous example can be accessed as:
 
       test "fetches current users", %{conn: conn} do
         # ...

        # Same as above, but receives the context as argument
        setup context do
          IO.puts("Setting up: #{context.test}")
          
          # We can simply return :ok when we don't want add any extra metadata
          :ok
        end

  Can return values to be merged into the `context`, to set up the state for
  tests. For more details, see the "Context" section shown above.

  `setup_all/1` callbacks are executed in a separate process than tests.
  All `setup_all/1` callbacks are executed in order in the same process.

  ## Examples

      # One-arity function name
      setup_all :clean_up_tmp_directory

      def clean_up_tmp_directory(_context) do
