-## Identifying functions
+## Identifying functions and documentation
 
 Functions in Elixir are identified by both their name and their arity. The arity of a function describes the number of arguments that the function takes. From this point on we will use both the function name and its arity to describe functions throughout the documentation. `round/1` identifies the function which is named `round` and takes `1` argument, whereas `round/2` identifies a different (nonexistent) function with the same name but with an arity of `2`.
 
+We can also use this syntax to access documentation. The Elixir shell defines the `h` function, which you can use to access documentation for any function. For example, typing `h round/1` is going to print the documentation for the `round/1` function:
+
+```iex
+iex> h round/1
+                             def round()
+                             
+Rounds a number to the nearest integer.
+```
+
+It also works with operators and other constructs (try `h +/2`). Invoking `h` without arguments displays the documentation for `IEx.Helpers`, which is where `h` and other functionality is defined.

 ## Booleans
 
 Elixir supports `true` and `false` as booleans:

 You can also use `is_integer/1`, `is_float/1` or `is_number/1` to check, respectively, if an argument is an integer, a float, or either.
 
-> Note: At any moment you can type `h()` in the shell to print information on how to use the shell. The `h` helper can also be used to access documentation for any function. For example, typing `h is_integer/1` is going to print the documentation for the `is_integer/1` function. It also works with operators and other constructs (try `h ==/2`).

 ## Atoms
 
 An atom is a constant whose name is its own value. Some other languages call these symbols:
