-- `element` returns the type of [Element](#elements) (e.g. Repeat, Sequence, Keyword, etc.). An element can be assigned to a variable; for instance in the example above `Keyword('hi')` was assigned to `k_hi`. With `element.name` the assigned name `k_hi` will be returned. Note that it is not a given that an element is named; in our example `Sequence` was not assigned, thus in this case the element has no attribute `name`.
+- `element` returns the [Element](#elements)'s type (e.g. Repeat, Sequence, Keyword, etc.).

 - `string` returns the string that is parsed.
 - `children` can return a node object containing deeper layered nodes provided that there are any. In our example the root node has an element type `Repeat()`, starts at 0 and ends at 24, and it has two `children`. These children are node objects that have both an element type `Sequence`, start at 0 and 12 respectively, and so on.
 
 
 ### Expecting
-`expecting` returns a Python set() containing elements which pyleri expects at `pos`. Even if `is_valid` is true there might be elements in this set, for example when an `Optional()` element could be added to the string. Expecting is useful if you want to implement things like auto-completion, syntax error handling, auto-syntax-correction etc. The following example will illustrate a way of implementation.

-In the above example we parsed an invalid string according to the grammar class. The `auto-correction()` method that we built for this example combines all properties from the `parse()` to create a valid string. The output shows every recursion of the `auto-correction()` method and prints successively the set of expected elements. It takes one randomly and adds it to the string. When the string corresponds to the grammar, the property `is_valid` will return `True`. Notably the `expecting` property still contains elements even if the `is_valid` returned `True`. The reason in this example is because of the [Repeat](#repeat) element.

 ## Elements
 Pyleri has several elements which are all subclasses of [Element](#element) and can be used to create a grammar.
