 ## `before` and `finally`
 `before` blocks are evaluated before the example and `finally` runs after the example.
 
-The blocks can return `{:shared, key: value, ...}` or (like in ExUnit) `{:ok, key: value, ...}`, so the keyword list will be saved in the dictionary and can be accessed in other `before` blocks, in the example, and in `finally` blocks through ['shared`](#shared).
-You can also use map as a second term in returned tuple: `{:shared, %{key: value, ...}}.
