Overview

Hi @shashigharti, is there something else to fix?

@roll Other issues are:

1. Python code will not be parsed and will be displayed as it is(screenshot1):

    schema = Schema('schema.json')
    schema.add_fied(Field(name='name', type='string'))
   

2. All text will be displayed in a single line (screenshot1). Can't add multiline text with examples.

And reload did not work while making changes to the doc blocks.
