Examples seem to be out of date

Hi, I am trying to use examples in the documentation, but many of them seem to be out of date. For example:

from prompt_toolkit.shortcuts import prompt
from prompt_toolkit.styles import Style

style = Style.from_dict({
    # User input.
    '':          '#ff0066',

    # Prompt.
    'username': '#884444',
    'at':       '#00aa00',
    'colon':    '#00aa00',
    'pound':    '#00aa00',
    'host':     '#000088 bg:#aaaaff',
    'path':     '#884444 underline',
})

def get_prompt():
    return [
        ('class:username', 'john'),
        ('class:at',       '@'),
        ('class:host',     'localhost'),
        ('class:colon',    ':'),
        ('class:path',     '/user/john'),
        ('class:pound',    '# '),
    ]

text = prompt(get_prompt, style=style)

causes exception: “AttributeError: type object ‘Style’ has no attribute ‘from_dict’”. I had issues with most of the examples I tried so far, but had satisfaction following this article: 4 Python libraries for building great command-line user interfaces.

Am I missing something? Is it maybe because examples are not updated to version 2?

Maybe it would be best to mention this in the README. For example, explaining that, to try the latest examples before the release of version 2.0, one can use this command to install the package:

pip install https://github.com/jonathanslenders/python-prompt-toolkit/archive/2.0.zip

Instead of:

pip install prompt_toolkit

agree @RobertoPrevato

I encounter the same issue.
